摘要:
Rovibrational absorption spectra of the N2-SO2 and OC-SO2 complexes in the v1 symmetric stretching region of SO2 have been measured in a supersonic slit jet expansion using a segmented rapid-scan quantum cascade laser spectrometer. The observed transitions are of c-type for both complexes. The possible tunneling splittings for N2-SO2 or OC-SO2 are too small to be resolved under our experimental conditions. The observed infrared transitions are assigned and fitted using a standard S-reduced Watson asymmetric top Hamiltonian, yielding accurate mo...
