ResumoThe Raman spectrum of benzene-d 6 vapour was excited in a multiple reflection cell by an Ar + laser and was photographed with a spectral slit width of ~0.15 cm −1 . Extensive structure (164 maxima) was observed for the ν 2 (C—C stretching) fundamental but only the S branch (39 maxima) of the ν 1 (C—D stretching) band was well-resolved. These totally symmetric bands were analysed and molecular constants determined from a least-squares fit. Three doubly degenerate bands were observed; ν 15 and ν 16 were unresolved, and in ν 17 only 19 lines could be measured. Consequently, no detailed analyses were possible but the values of some molecular constants were estimated.
