Abstract
The near infrared $\nu_{2}+\nu_{5}{^{1}}$ combination bands of $OC-H^{35}Cl$ and $OC-H^{37}Cl$ have been recorded using a high frequency wavelength modulation diode laser supersonic jet spectrometer. In addition, the static gas phase spectra of the associated $\nu_{2}+\nu_{5}{^{1}}-\nu_{5}{^{1}}$ and $\nu_{2}+ 2\nu_{5}{^{1}}-2\nu_{5}{^{1}}$ hot bands in $OC-H^{35}Cl$ have been recorded using Fourier transform infrared absorption spectroscopy. The combined results permit evaluation of rovibrational constants for the low frequency intermolecular bending vibration of the $OC-H^{35}Cl$ isotopomer (in $cm^{-1}):\nu_{5}{^{1}} = 48.9953(2);B(\nu_{5}{^{1}}) = 0.565731(6),Dj \nu_{5}{^{1}} = 1.906 \times 10^{-7} (6)$ and $q\nu_{5}{^{1}}1 = 0.0001466(2)$.
