 Title: VIBRATIONAL DEPENDENCE OF HYDROGEN-BROADENED HALFWIDTHS OF WATER VAPOR TRANSITIONS Creators: Gamache, Robert R.; Lynch, R. Issue Date: 1996 Abstract: The pressure broadened halfwidth of water vapor transitions in the ground, $\nu_{2}$, $\nu_{1}$, and $\nu_{3}$ bands are calculated with hydrogen as the perturbing species using the fully complex Robert and Bonamy $theory.^{a,b}$ The assumed intermolecular potential is a combination of electrostatic, Lennard-Jones 6-12 atom-atom (expanded to 4th order), induction, and dispersion terms. The results are compared with the measurements of Brown and Plymate $^{c}$ and the vibrational dependence of the halfwidths investigated.
