H(2)O(2) photoproduction inside H(2)O and H(2)O:O(2) ices at 20–140 K

We report the results of laboratory measurements of H(2)O(2) production inside thin (50 nm thickness) H(2)O and H(2)O:O(2) ice samples irradiated by 121.6 nm photons at different temperatures. In the case of H(2)O ice, H(2)O(2) is formed at the temperatures below 60 К. In the case of H(2)O:O(2) ice,...

description We report the results of laboratory measurements of H(2)O(2) production inside thin (50 nm thickness) H(2)O and H(2)O:O(2) ice samples irradiated by 121.6 nm photons at different temperatures. In the case of H(2)O ice, H(2)O(2) is formed at the temperatures below 60 К. In the case of H(2)O:O(2) ice, H(2)O(2) is formed in the 20–140 К range. For H(2)O:O(2) = 9:1 ice, we derived H(2)O(2) photochemical quantum yield as a function of sample irradiation temperature. The obtained data can be used for evaluation of H(2)O(2) photoproduction at the surface of astrophysical water ice bodies and inside the particles of Noctilucent Clouds in the Earth’s atmosphere.
