Abstract: The pressure dependence of the absorption spectrum of hydrogen molecules inside pores of an aerogel has been found. Two components with linear and quadratic pressure dependences have been revealed. It has been assumed that the first component can be attributed to the absorption of an individual molecule near the surface of pores, whereas the second component is due to intermolecular interaction. A method has been proposed to estimate in the first approximation the size of pores from the absorption spectrum.
