Abstract: | The infrared spectra of the a-type transitions of the ν2 and ν3 bands of HO35Cl and HO37Cl have been obtained under high resolution. Line assignments of both bands have been made, and the spectroscopic constants have been obtained for both bands using a Watson Hamiltonian. Lines of the Ka = 5 subband of the ν2 band of the HO35Cl molecule were found to be slightly shifted by an interaction with the Ka = 4 level of the 2ν3 vibrational state. The b-type transitions permitted for both bands were too weak to observe. Relative intensities of selected lines of both bands have been measured, and empirical Herman-Wallis factors have been determined. |
