This volume, the second in the Methods in Pharmacology series, contains some of the physical methods which either have been or could be applied to pharmaco- logical problems. A major emphasis has been placed on spectroscopic techniques, particularly those, such as optical rotatory dispersion and circular dichroism, fluorescence spectroscopy, magnetic resonance spectroscopy, ultraviolet absorption spectroscopy, stopped flow and relaxation spectrometry, Mossbauer spectroscopy, light scatter and x-ray crystallography, that can be used to study drug interactions with biological systems at a...
