High‐resolution quasi‐continuous wave inverse Raman spectrometer. Spectrum of CH3D in the C-D stretching region

Abstract
The construction of a spectrometer for high‐resolution stimulated Raman spectroscopy is reported and the accuracy of wavenumber determination achievable is discussed. A Doppler‐limited spectrum of the CD stretching band (Q‐branch) of the CH3D molecule in the 2200 cm−1 region was recorded. Most of the observed transitions have been assigned and some rotational‐vibrational constants have been refined.
