Abstract:
The literature experimental data on relaxation of (103) and (100-001) states of the H2O molecule in pure water vapor and in its mixture with nitrogen and air are analyzed. Based on the model of the process of intramolecular energy exchange, we estimated relaxation rate constants for (0V20) band levels, as well as the mean energy transferred by the H2O molecule collisionally excited to the (103) state. The mean collisional energy transferred is from 15-35 cm-1 (at excitation energy up to 3000-4000 cm-1) to 100 cm-1 (at excitation energy of 14400 cm-1).
