Abstract
Recent results of sub-Doppler IR diode laser spectroscopy of freons in a supersonic jet are reported. The v1 parallel band of CCl3F has been recorded at a rotational temperature of about 20 K, in a supersonic slit jet expansion. A detailed rotational analysis has been performed yielding band origins and rotational constants for the three most abundant isotopomers C35Cl3F, C35Cl2ClF and C35Cl37Cl2F. The CHF2Cl molecule has two strong fundamental bands in the atmospheric window, v3 at 1108.7278 cm-1 and v8 at 1127.2844 cm-1. A preliminary analysis of the v3 band of the CHF237Cl isotopic species will be presented.
