Description

Determination of Organic Structures by Physical Methods, Volume 3 is a seven-chapter text that describes the refinements of some established physical methods for organic structure determination. Each chapter of this book examines specific physical method, including photoelectron spectroscopy, X-ray diffraction, optical rotary dispersion, circular dichroism, mass spectrometry, and electron spin resonance and NMR spectroscopies. The historical developments, instrumentation, and applications to organic chemistry of these methods are discussed. This work will be of value to organic and analytical chemists and researchers.
