Abstract

New high-resolution experimental data are reported on the linestrengths and self-pressure-broadened Lorentzian widths for the P₁(1)-P₁(10), R₁(0)-R₁(15), and P₂(13)-R₂(12) vibration-rotation lines in the fundamental and the first overtone absorption bands of HI. An improved dipole moment expansion as a function of the reduced nuclear displacement is generated and compared with the available ab initio calculations. A new set of the Herman - Wallis coefficients is obtained, which is in a better agreement with theory than previously published results.
