Photochemical model of impact-produced lunar atmosphere
  The Lunar Prospector mission detected hydrogen-containing compounds in the lunar polar regions. We have considered the comet hypothesis of the origin of polar volatiles on the Moon. In the present paper we use our model of a comet impact with photochemical processes to be included to estimate chemical composition of volatiles which can be captured by the cold traps.
