Raman Spectra from Acetone

Abstract

Measurements of Raman spectra from acetone have been published in a recent paper [1]. These measurements were so interpreted that out of thirteen modified lines, twelve corresponded to frequencies of observed infra-red absorptions, the thirteenth lying outside the range of the infrared measurements. This result is surprising; for the occurrence of frequency shifts in Raman effect without the appearance of the corresponding infra-red absorptions is a very common phenomenon. We have examined Raman spectra from acetone; and as both our measurements and our interpretation disagree with those mentioned above, it seems desirable to report them.
