Abstract

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