Abstract

Accurate values for the Lambert absorption coefficients of water have been determined in the atmospherically important frequency region of 3000–934 cm−1 (3.333–10.707 μm). These values were calculated at every 2 wave numbers from linear regression of 13 spectra obtained by using both transmission and internal reflection techniques with varying sample thicknesses. Correlation coefficients (R2) 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 measurements.
