Effective dipole moment and band intensities of nitrous oxide

The effective Hamiltonian and effective dipole moment approach is applied to the band intensities problem for nitrous oxide. Using eigenfunctions of our reduced effective Hamiltonian (J. Mol. Spectrosc. 168, 390-403 (1992)), the experimental rotationless electric-dipole transition moments of R. A. Toth (Appl. Opt. 32, 7326-7365 (1993)) for the (N2O)-N-14-O-16 allowed bands lying in 900-3600 cm(-1) region have been fitted to the effective dipole moment parameters. The obtained parameters have allowed us to reproduce the experimental rotationless electric-dipole transition moments practically within the experimental accuracy and to predict those for the forbidden Delta e(2) = 2 bands with good accuracy. The fitted parameters can be used also for prediction of intensities of new hot hands lying in the 900-3600 cm(-1) region. (C) 1995 Academic Press, Inc.
