This monograph presents the molecular theory and necessary tools for the study of solvent-induced interactions and forces. After introducing the reader to the basic definitions of solvent-induced interactions, the author provides a brief analysis of the statistical thermodynamics. The book thoroughly overviews the connection of those interactions with thermodynamics and consequently focuses on specifically discussing the hydrophobic-hydrophilic interactions and forces. The importance of the implementation of hydrophilic interactions and forces in various biochemical processes is thoroughly analyzed, while evidence based on theory, experiments, and simulated calculations supporting that hydrophilic interactions and forces are far more important than the corresponding hydrophobic effects in many biochemical processes such as protein folding, self-assembly of proteins, molecular recognitions, are described in detail. This title is of great interest to students and researchers working in the fields of chemistry, physics, biochemistry, and molecular biology.

This textbook provides a unique instructional resource in experimental Physical Chemistry with case studies based on data taken from the scientific literature. Platform-independent software that generates individualized data sets for student practice and assessment is included. Case Studies in the Virtual Physical Laboratory can be used to • Create online virtual laboratory courses in Physical Chemistry. • Supplement instruction in the lecture hall. • Complement hands-on projects in face-to-face laboratory courses.  The case studies cover states of matter, thermochemistry, phase equilibria, reaction equilibria, chemical kinetics, electrolyte solutions, and activity coefficients. They are written to be self-contained to give flexibility in the choice of projects. The pedagogical approach in each case study is to use the given data in direct instruction followed by the analysis of the synthetic data as individualized tasks.  Only open-source software tools are needed to analyze data. Each case study contains a thorough discussion of the theoretical principles underlying the experiment and data, the character of the data to be analyzed, and methods appropriate for the analysis of the data. The accompanying software has been written to allow the production of many data sets without risking duplication, yet the synthetic data can be regenerated if the files are lost or become corrupted. Software programs were written in Fortran 95 and are distributed as a suite of executable programs for Intel-based computers running Windows, MacOS, or Linux. This book will be of particular interest and usefulness to students and instructors in upper-division undergraduate physical chemistry courses.

This monograph offers a unique approach to understanding thermodynamics by blending practical experience, a mathematically rigorous foundation, and historical insights.

This monograph offers a unique approach to understanding thermodynamics by blending practical experience, a mathematically rigorous foundation, and historical insights. It presents the evolution of thermodynamics, demonstrating that the functions, equations, relationships, and quantities didn't simply materialize but were rooted in the human experience of heat and cold. While equilibrium thermodynamics is the primary focus, time is integrated as a fundamental element, distinguishing this from traditional treatments. Readers will find familiar heat-related experiences transformed into model equations, revealing the natural emergence of fundamental thermodynamic concepts. These essentials are then distilled into simple axioms summarizing the core principles of equilibrium thermodynamics. The book goes beyond macroscopic descriptions, delving into microscopic connections at the atomic and molecular levels. It is suitable for a diverse readership, including students in science and technology, professionals looking to refresh their knowledge of thermodynamics, and those interested in exploring advanced, non-equilibrium thermodynamics. While it caters to a broad audience, it is particularly beneficial for individuals in chemistry and chemical engineering, requiring only a basic understanding of calculus.

This book provides a concise overview of the photophysics and spectroscopy of bio chromophore ions. The book "Photophysics of Ionic Biochromophores" summarizes important recent advances in the spectroscopy of isolated biomolecular ions in vacuo, which has within the last decade become a highly active research field. Advanced instrumental apparatus and the steady increase in more and more powerful computers have made this development possible, both for experimentalists and theoreticians. Applied techniques described here include absorption and fluorescence spectroscopy, which are excellent indicators of environmental effects and can thus shed light on the intrinsic electronic structures of ions without perturbations from e.g. water molecules, counter ions, nearby charges, and polar amino acid residues. When compared with spectra of the chromophores in their natural environment, such spectra allow to identify possible perturbations. At the same time gas-phase spectra provide important benchmarks for quantum chemistry calculations of electronically excited states. This volume focuses on biological systems from protein biochromophores, e.g. the protonated Schiff-base retinal responsible for vision, and individual aromatic amino acids to peptides and whole proteins, studied using visible, ultraviolet and vacuum ultraviolet light. Work on DNA nucleotides and strands that are amenable to mass spectrometric studies because of the negatively charged sugarphosphate backbone are also presented. DNA strands represent an example of the interplay between multiple chromophores, which is even harder to model correctly than just single chromophores due to spatially extended excited states and weak coupling terms. The experimental techniques used to measure spectra and commonly used theoretical methods are described with a discussion on limitations and advantages. The volume includes an updated status of the field and interesting future directions such as cold ionspectroscopy.

Astrochemistry and Astrobiology is the debut volume in the new series Physical Chemistry in Action. Aimed at both the novice and experienced researcher, this volume outlines the physico-chemical principles which underpin our attempts to understand astrochemistry and predict astrobiology.

Eight further chapters address specific topics, encompassing basic theory and models, up-to-date research and an outlook on future work. The last chapter examines each of the topics again but addressed from a different angle. Written and edited by international experts, this text is accessible for those entering the field of astrochemistry and astrobiology, while it still remains interesting for more experienced researchers.

This book focuses on current applications of molecular quantum dynamics. Examples from all main subjects in the field, presented by the internationally renowned experts, illustrate the importance of the domain. Recent success in helping to understand experimental observations in fields like heterogeneous catalysis, photochemistry, reactive scattering, optical spectroscopy, or femto- and attosecond chemistry and spectroscopy underline that nuclear quantum mechanical effects affect many areas of chemical and physical research. In contrast to standard quantum chemistry calculations, where the nuclei are treated classically, molecular quantum dynamics can cover quantum mechanical effects in their motion. Many examples, ranging from fundamental to applied problems, are known today that are impacted by nuclear quantum mechanical effects, including phenomena like tunneling, zero point energy effects, or non-adiabatic transitions. Being important to correctly understand many observations in chemical, organic and biological systems, or for the understanding of molecular spectroscopy, the range of applications covered in this book comprises broad areas of science: from astrophysics and the physics and chemistry of the atmosphere, over elementary processes in chemistry, to biological processes (such as the first steps of photosynthesis or vision). Nevertheless, many researchers refrain from entering this domain. The book "Molecular Quantum Dynamics" offers them an accessible introduction. Although the calculation of large systems still presents a challenge - despite the considerable power of modern computers - new strategies have been developed to extend the studies to systems of increasing size. Such strategies are presented after a brief overview of the historical background. Strong emphasis is put on an educational presentation of the fundamental concepts, so that the reader can inform himself about the most important concepts, like eigenstates, wave packets, quantum mechanical resonances, entanglement, etc. The chosen examples highlight that high-level experiments and theory need to work closely together. This book thus is a must-read both for researchers working experimentally or theoretically in the concerned fields, and generally for anyone interested in the exciting world of molecular quantum dynamics.
