Abstract:
Experimental study of the HF first overtone vibration-rotational absorption spectral line profile (the transition 0-2R(0)) broadened by Ar (mixture HF : Ar = 1 : 150, T = 295°K, P = 10ё300 Torr) is performed using the method of near IR diode laser spectroscopy. Tunable distributed feedback fiber diode laser was used as a radiation source in the two-channel spectrometer (wavelength l is ~ 1.284mm, spectral tuning range Dl= 1.5-2.0 cm-1, a power of output radiation of 15 mW, spectral half-width of radiation emission line is ~5 МHz). Broadening and shifting coefficients of considered HF line are determined by using traditional spectral profiles of Voigt, Rautian, and Galatry.
