This book was first published in 1973. The Hammett equation is used for the elucidation of intramolecular interactions, electronic or steric, and for examination of the influence of substituents on rates or positions of equilibrium of organic reactions. It is used in the investigation of reaction mechanisms, where it is often combined with other physiochemical techniques, providing a consistent and convincing rationale of many reaction patterns. This book was written to provide senior undergraduates and first-year graduate students with a guide to the implications of these properties. Each chapter concludes with a series of problems, all drawn from research papers.

In Chaha the impersonal and Sg. 3m. object suffixes labialize the nearest preceding plain noncoronal consonant. Furthermore a consonant will become identical to the next following consonant if it can do so by becoming labialized or palatalized. An attempt to formulate these rules in an economical way that reflects universal constraints on action at a distance leads to the proposal that the notation Xo be abolished from generative phonology and that in its stead there be used structural descriptions of the more restricted for [X [Y] [Z] ], having the meaning of [X, Y][-X]0 [X, Z] .
