Raman Spectra of Deuterobenzenes and the Structure of Benzene

Abstract

THE letter by Klit and Langseth in NATURE of June 8 (p. 956), recording Raman frequencies of some deuterobenzenes, leads us to report our own results so far as these overlap, although we had wished to reserve publication until the problem of which these spectra supply only part of the answer had been fully solved. Klit and Langseth record 8 lines for C₆D₆, and 1 for each of G₆H₅D and C₆HD₅ (not obtained pure). This note relates to C₆D₆ and C₆H₅D (both pure); we have not prepared C₆HD₅; we have, however, examined 1:4–C₆H₄D₂ and hope to study 1:3:5–C₆H₃D₃ also, for the following reason.
