Pressure broadening coefficients for rotational transitions of water in the 380-600 cm(-1) range. Steyert, D., W.; Wang, W., F.; Sirota, J., M.; Donahue, N., M.; and Reuter, D., C. J. Quant. Spectrosc. Radiat. Transf., 72:775-782, 2002. abstract bibtex We present results of recent experiments on the
pressure broadening of pure rotational transitions of (H2O)-O-16
water in the 400-600 cm(-1) range by nitrogen and oxygen. The
average broadening coefficient is about 0.056 cm(-1)/atm for N-2
and about 0.029 cm(-1)/atm for O-2, however, as expected, the
broadening coefficient varies as a strong function of transition.
In general, the broadening decreases with increasing J and K-a,
with a stronger dependence on K-a than on J. On average, air
broadening coefficients obtained from the coefficients presented
here are about 10% lower than those found in HITRAN '96, although,
as detailed below, the differences are a function of quantum
number. (C) 2002 Elsevier Science Ltd. All rights reserved. C1 Univ
