| Abstract: | Using a combination of photostimulated desorption and resonance-enhanced multiphoton ionization techniques, OH radicals photodesorbed from amorphous solid water at low temperatures are detected. It was found that the OH photodesorption can be caused by a one-photon process on the surface even at 532 nm, where both isolated OH and H2O are transparent. Quantum chemical calculations reveal that the electronic excitation of OH dramatically changes depending on the adsorption sites and the number of surrounding H2O molecules, and that OH having three hydrogen bonds with neighboring H2O molecules can absorb photons of around 532 nm, which supports the experimental findings. |
