Study of the HF overtone line profile broadened by Ar, Xe, Kr, N2 using near-IR region diode laser spectroscopy

The profile of the 0-2 R(0) overtone vibrational-rotational absorption line of HF molecules in mixtures with Ar, Xe, Kr, N 2 is experimentally studied using near-IR-range diode laser spectroscopy. The coefficients of collisional broadening, shift, and collisional narrowing of the HF line in these bu...

Summary:The profile of the 0-2 R(0) overtone vibrational-rotational absorption line of HF molecules in mixtures with Ar, Xe, Kr, N 2 is experimentally studied using near-IR-range diode laser spectroscopy. The coefficients of collisional broadening, shift, and collisional narrowing of the HF line in these buffer gases are determined using the Voigt, Rautian, and Galatry profiles.
