The spectrum of acetone‐d6 of over 90 percent purity has been photographed in the region 2000–1300A, with a dispersion of 4.14A per mm. Data for the transition at about 51,000 cm−1 are presented together with new data on acetone in the same region. A discussion of the normal state of the acetones is given, and an analysis is made of the electronic spectra. It is shown that no vibrational frequency near 1200 cm−1 appears in the excited state of acetone‐d6 and that this frequency in acetone cannot be ascribed to the C–O vibration.

There are two low frequency lines 587 and 731 cm−1 of very low intensity and unknown depolarization which do not fall into any assignment. Lines corresponding to these do not appear in the Raman spectrum of deuteroacetone. The acetone frequency 901 cm−1 appears strongly in the infra‐red (880 cm−1) and may be associated with internal rotation [cf.
