RESUMEN
During the descent to the surface of Venus, the large probe infrared radiometer measured the net thermal radiative flux in several spectral bandpasses. Preliminary analysis has permitted us to estimate (i) the infrared extinction coefficient profile attributable to aerosols, with respect to their visible profile, in the upper atmosphere of Venus and (ii) the water vapor mixing ratio below the clouds. An indication of the composition of a multicomponent cloud is seen in the data from the spectral bandpass from 6 to 7 micrometers.
RESUMEN
Values for mid-IR integrated band intensities of gaseous N(2)O(5) were determined at room temperature. The absorptions studied were at 1720, 1246, 743, and 557 cm(-1). The integrated intensities were 2204, 581, 685, and 699 atm(-1)-cm(-2), respectively. Implications of these results for the stratospheric detection of N(2)O(5) are discussed.
RESUMEN
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.
RESUMEN
A new atlas of CH(4) lines in the 1120-1800-cm(-1) region has been generated, based on laboratory spectra taken with a Nicolet interferometer at 0.06-cm(-1) resolution with 635-cm path length at pressures of 0.98 Torr, 4.86 Torr, and 19.97 Torr. A compilation of line positions and line intensities includes 1339 CH(4) lines, several hundred of which have not been previously observed.
