SPECTRAL-LINE PARAMETERS FOR THE O-2 HERZBERG-I BAND SYSTEM

Spectral line parameters required for line-by-line spectral syntheses have been calculated for the weak Herzberg I band system of O2. The line locations were calculated with constants from Borrell, Borrell, and Ramsay (Can. J. Phys. 64, 721 (1986)). and agree closely with these authors' measured wave numbers. Line strengths were calculated using formulae given by Lewis and Gibson (Can. J. Phys. 68, 231 (1990).) but empirically modified to concur with the relative strengths measured by Herzberg (Can. J. Phys. 30, 185 (1952).), the only ones found in the literature. Line strengths and line widths are both very uncertain and need to be revised as more information becomes available. Line parameters were calculated for transitions from the upsilon" = 0, 1, and 2 vibrational levels; a strength cutoff of 1.0 x 10(-40) cm2 cm-1 per molecule was imposed.
