Raman Spectra of Dialkyl Ketones

Abstract

Displacements, estimated intensities and depolarization factors have been measured for acetone, 2,6‐dimethyl‐4‐heptanone, 5‐nonanone, 7‐tridecanone, 8‐pentadecanone and 5‐tetradecanone. The results for acetone are compared with the previous data: Eight lines previously reported by one or more investigators are believed to be non‐existent. A new weak line was observed at 1676 cm⁻¹. The depolarization factors obtained agree well with those reported by Simons, except that the 1356 line was found to be considerably less polarized and data for five additional lines were obtained.
