Neon-, krypton-, and xenon-broadened spectral lines of water vapor

摘要

Intermolecular-interaction potentials for the H2O-Ne, H2O-Kr, and H2O-Xe systems have been determined from experimental broadening coefficients gamma found for vibrational-rotational absorption lines in the nu(2) band of water-vapor molecules in the corresponding mixtures at a temperature of T = 296 K. The rotational and vibrational corrections to the effective potentials are calculated. Broadening coefficients gamma of the absorption lines of the H2O molecule are calculated for a wide range of rotational quantum numbers in the temperature range 300 K ae D cent ae 600 K. A comparative analysis of the temperature dependences of the calculated broadening coefficients for the potentials in use is performed.
