Systematic interpretation of Raman spectra of organic compounds. III—carbonyl compounds

The Raman spectra of 220 carbonyl‐containing compounds have been recorded. The characteristic frequencies are reported. Correlations between frequencies and structure have been investigated. The collected data have been incorporated into a formerly developed and outlined interpretation system for CH, OH and O compounds. Difficulties in modifying the old system are discussed and a schematic survey of the new system is given.
