Abstract
Rovibrational analysis of the $\nu_{1}$ and $\nu_{2}$ vibrational bands of $OC-H^{35}Cl$ and $OC-H^{37}Cl$ have been carried out using continuous supersonic-jet, Fourier transform, infra-red absorption spectroscopy. The following molecular parameters were determined (in $cm^{-1}$). For $OC-H^{35}Cl: \nu_{1}=2851.76061(21): B^{\prime}_{1}= 0.0560443(31): D^{\prime}_{1}=1.795(80) \times 10^{-7}: \nu_{2}=2155.50001(13): B^{\prime}_{2}=0.0554824(10): D^{\prime}_{2}=1.650(15) \times 10^{-7}$: For $OC-H^{37}Cl: \nu_{1}=2849.67217(54): B^{\prime}_{1}=0.0547611(55): D^{\prime}_{1}=1.63(11) \times 10^{-7}: \nu_{2}=2155.50626(62):B^{\prime}_{2}=0.0542013(21): D^{\prime}_{2}=1.48(16) \times; 10^{-7}$. Additionally, ro-vibrationally resolved spectra of the weakly bound complexes of $Ar-HCl, N_{2}-HCl$ and $(HCl)_{2}$ will also be presented to illustrate the utility that SSJ-FTIR offers to the spectroscopic studies of gas-phase molecular species.
