A STUDY OF THE INTERMOLECULAR NU(1)(5) VIBRATION IN OC-(HCL)-CL-35 BASED ON NEAR-INFRARED SPECTROSCOPY

The near infrared nu(2)+nu(5)(1) combination bands of OC-(HCl)-Cl-35 a nd OC-(HCl)-Cl-37 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)(2)-2 nu(5)(2) hot bands in OC-(HCl)-Cl-35 have been rec orded using Fourier transform infrared absorption spectroscopy. The co mbined results permitted the evaluation of the hand origin of 48.9944( 2) cm(-1), a rotational constant of 0.0565731(6) cm(-1), a distortion constant of 1.906 X 10(-7)(6) cm(-1) and the Coriolis coupling constan t of 0.0001466(2) cm(-1) for the low frequency intermolecular bending vibration of the OC-(HCl)-Cl-35 isotopomer.
