Abstract
Assignments have been carried out for the 2ν3/(ν3+ν6)/2ν6 (triad)←ground state overtone bands and the triad←ν3/ν6 hot‐band system of CHD3. A vibrational extrapolation method, using correspondences between a spherical‐tensor formalism and the more conventional description of symmetric‐rotor spectra, was used to facilitate the assignment and analysis of these bands. The resulting assignments have been confirmed by time‐resolved double‐resonance measurements.Keywords
