Abstract
We present a laser absorption technique to measure the vapor pressure of ice. This method is referenced to the triple point state of water and uses frequency-stabilized cavity ring-down spec- troscopy to probe four rotation-vibration transitions of H16 2 O at wave numbers near 7180 cm¡1. Laser measurements are made at the output of a temperature-regulated standard humidity genera- tor which contains ice. The dynamic range of the technique is extended by measuring the relative intensities of three weak/strong transition pairs at ¯xed ice temperature and humidity concentra- tion. Our preliminary results agree with Wexler's ice vapor pressure correlation [A. Wexler, J. Res. NBS 81A, 5 (1977)] over the temperature range 0 ±C to ¡70 ±C to within 0.5%.Citation
