THE RAMAN SPECTRUM OF ETHANE-1,1,1-d3

Abstract

The Raman spectrum of CH3–CD3 at 1 atm pressure was photographed with a spectral resolution of ~0.3 cm−1. The nondegenerate ν1 and ν3 and the doubly degenerate ν7 and ν11 fundamentals were observed. Analyses of the rotational structure of the ν3 and ν7 bands gave the rotational constants, B0 = 0.549 1 ± 0.000 3 cm−1 and A0 = 1.7809 ± 0.0016 cm−1, respectively. These are consistent with rotational constants previously obtained for C2H6 and C2D6.
