Accurate values for the Lambert absorption coefficients of water have
been determined in the atmospherically important frequency region of 3
000-934 cm(-1) (3.333-10.707 mu m). These values were calculated at ev
ery 2 wave numbers from linear regression of 13 spectra obtained by us
ing both transmission and internal reflection techniques with varying
sample thicknesses. Correlation coefficients (R(2)) varied from 0.998
to 0.826 and estimated errors in the measured values ranged from 1% to
10%. Results are compared with those reported earlier from single mea
surements.
