DF AND HF LASER SPECTRA

Abstract

A pulsed laser was used as a source to study DF and HF infrared laser spectra with a grating spectrometer. The rotational structure observed for the 1-0, 2-1, and 3-2 bands of DF, and the 1-0 and 2-1 bands of HF has been measured by following a procedure similar to that used for the CO laser $spectra.^{1}$ Molecular constants derived by combining these laser measurements with other available data will be presented.
