Abstract:

The absorption by water vapor between 2800 and 4500cm has been investigated. Spectra have been obtained for samples at pressures from 0.48 torr to 10 atm, and with absorber thicknesses varying from .0008 x to 0.7 gmcm. Transmission spectra are shown along with extensive tables of transmittance, integrated absorptance, and the integrated absorption coefficient. Results are presented for samples chosen to provide information about the strengths, widths, and shapes of many of the absorption lines. The combined strength of the nu sub 1 and nu sub 3 bands has been found to be 28 15000 cmgm and the strength of the 2 nu sub 2 is 3.5 0.7 x 103 cmgm.
