Spectrcscopic Arguments for Isomeric Structures in a-Chloro-Acids

Abstract

IN a recent paper, Renard¹ has applied a method by which the qualitative analysis of the hydrolysates of proteins seems easily realized. The first step of the process consists in transforming the α-mono-amino mono-carboxylic acids resulting from hydrolysis into α-chloro-acids; the latter having been separated into different groups by fractional distillation, Raman analysis is used to identify the compounds. The fundamental assumption made by Renard is that the spectrum of the mixture results from the superposition of the spectra of the constituent acids.
