Rovibrational analysis of the $\nu 1$ and $\nu 2$ vibrational bands of $OC-H35Cl$ and $OC-H37Cl$ have been carried out using continuous supersonic-jet, Fourier transform, infra-red absorption spectroscopy. The following molecular parameters were determined (in $cm-1$). For $OC-H35Cl:\nu 1=2851.76061(21):B1\prime =0.0560443(31):D1\prime =1.795(80)\times 10-7:\nu 2=2155.50001(13):B2\prime =0.0554824(10):D2\prime =1.650(15)\times 10-7$: For $OC-H37Cl:\nu 1=2849.67217(54):B1\prime =0.0547611(55):D1\prime =1.63(11)\times 10-7:\nu 2=2155.50626(62):B2\prime =0.0542013(21):D2\prime =1.48(16)\times ;10-7$. Additionally, ro-vibrationally resolved spectra of the weakly bound complexes of $Ar-HCl,N2-HCl$ and $(HCl)2$ will also be presented to illustrate the utility that SSJ-FTIR offers to the spectroscopic studies of gas-phase molecular species.
