Spectroscopic line parameters for the nu(6) band of carbonyl fluoride.

New measurements and analysis of high resolution(0.0025 cm(-1)) laboratory spectra of the carbonyl fluoride v6 band are described. The data are used to generate line parameters suitable for high resolution atmospheric studies.

Intensity of the hydrogen peroxide upsilon(6)(b) band around 1266 cm(-1).

Laboratory spectra of the upsilon(6)(b) band of H(2)O(2) at 1266 cm(-1) have been obtained at a resolution of 0.06 cm(-1) and at temperatures ranging from 278 to 294 K. A total band intensity of 375 +/- 17 cm(-2) amagat(-1) is determined from the spectra. Special techniques to handle the H(2)O(2) samples in a way that minimizes abundance determination errors are discussed.

Quantitative Studies of HNO(3) Vapor Absorption in the 1700-2636-A Wavelength Region.

Quantitative measurements were made in the 1700-2636-A wavelength interval at 22 degrees C of the pure HNO(3) vapor absorption spectrum. Absorption coefficients, which were found to be both pressure and length dependent, were determined using six absorption cell lengths between 0.1 cm and 10.0 cm, and numerous gas pressures in the 0.0004-0.066-atm range. The statistical spectral band model with a Voigt line profile was applied to the data and the band model parameters were derived. The results were used to estimate the absorption of uv radiation by stratospheric HNO(3).

Statistical Band Model Parameters and Integrated Intensities for the 5.9-mu, 7.5-mu, and 11.3-mu Bands of HNO(3) Vapor.

Quantitative absorption measurements of the 5.9-mu, 7.5-mu, and the 11.3-mu bands of pure HNO(3) vapor were carried out at 40 degrees C. Use was made of absorption cells of various lengths in order to obtain curves of growth. The statistical spectral band model was applied, and band model parameters and integrated intensities were derived.
