Abstract
The results of the measurements of H2 molecules concentration into aerogel (SiO2) nanopores with diameter 20 nm are presented. The standard gasometric method was used. The experimental data on H2 molecule concentration together with the data on integral intensity of H2 collision induced absorption band 0-1 were applied for estimation of the absorption cross section at the band maximum.
