摘要: Using the optothermal technique we have measured ν1 fundamental of CF3CCH in a collimated molecular beam. A linear least-squares fit to unperturbed K subbands with band origin fixed at 3329.85 cm–1 gives rotational constants as B′= 0.095 853 9(17) and ΔA=–0.000 008 8(22) cm–1. The perturbed are best by an anharmonic coupling background state interaction matrix element ca. 0.005 Several other perturbations noticed spectrum.
