Laser Stark and interferometric studies of thioformaldehyde and methyleneimine

Abstract

Laser Stark and optical–optical double resonance experiments have been carried out on H₂CS and on D₂CS, and rotational and vibrational constants obtained for the ν₃ bands. The dipole moments in the ν₃ and ν₄ states of H₂CS, and in the v₃ and ground states of D₂CS have been measured. Interferometric spectra have been obtained and analysed for the ν₄, ν₅ and ν₆ bands of CH₂NH, and some laser Stark and interferometric spectra obtained in the perturbed 10 µm region.
