Ronald Y. Dong – författare

Intended for researchers and students in physics, chemistry and materials science, this work aims to provide the necessary background information and sufficient mathematical and physical detail to study research literature in nuclear magnetic resonance studies of liquid crystals. This second edition, updated throughout, incorporates many new references, corrects typographical errors, and includes new mathematical appendices.

Liquid crystals have become ubiquitous in the displays for electronic devices, ranging from wrist watches to laptop computers. Nuclear magnetic resonance has become one of the important techniques for determining their structures and properties. Intended for researchers and students in physics, chemistry and materials science, this book provides the necessary background information and sufficient mathematical and physical detail to study the current research literature. The book begins with a survey of liquid crystal phases and field effects and with an introduction to the basic physics of nuclear magnetic resonance; it then discusses orientational ordering and molecular field theories for various liquid crystal molecules and NMR studies of uniaxial and biaxial phases. Subsequent chapters consider spin relaxation processes (using a semiclassical approach) and rotational, translational, and internal molecular dynamics of liquid crystals. The final chapter discusses two-dimensional and multiple-quantum NMR spectroscopies and their application in elucidating liquid crystal properties. This second edition, updated throughout, incorporates many new references, corrects typographical errors, and includes new mathematical appendices.

Liquid crystals have become ubiquitous in the displays for electronic devices, ranging from wrist watches to laptop computers. Nuclear magnetic resonance is one of the important mechanisms for determining their structures tures and properties. This book covers NMR techniques used in studying liquid crystals and present up to date results from such studies. Ronald Dong has worked on NMR in liquid crystals for much of his professional career. Topics covered include: Nuclear spin dynamics, orientational order, molecular field theories of liquid-crystal molecules, nuclear spin relaxation, spin relaxation, rotational and translational dynamics, internal dynamics of liquid-crystal molecules, NMR in liquid crystals; an appendix covers rotations, Euler angles and Wigner rotation matrices.
