Spectroscopy and Laser Applications

Advantage has been taken of the ability to matrix isolate D2O in H2O ice Ic to determine the activation energy for proton transfer. The value computed from spectroscopic data is 9.3 ± 0.3 kcal which is comparable to accepted values of Ea for conduction (8.5–9.0 kcal) and the excitation energy for the OH stretching mode in H2O ice Ic (≈ 9.2 kcal).
