Infrared Absorption by H2O and N2O

Abstract

The infrared absorption by samples of H2O and H2O + N2 has been studied in three spectral regions, 1630-2290/cm, 1250-1445/cm and 430-822/cm. The samples cover a wide range of path lengths and pressures with temperatures up to 433 K. The emphasis had been on the continuum absorption in several narrow spectral intervals where most of the absorption results from lines centered more than 1/cm from the point of observation. Absorption by the distant wings of N2-broadened H2O lines is less relative to self-broadened H2O lines than it is within a few wavenumbers of the line centers. This result is consistent with results published previously for other spectral regions.
