Abstract
Room-temperature absorption spectra of H2 in nanoporous aerogel with a pore diameter of ∼20 nm have been studied on a Fourier spectrometer in the spectral range of 4000–4800 cm−1. Absorption at the forbidden transitions of the 0–1 vibrational band has been observed. The recorded spectra of H2 in aerogel have been compared with the spectra of free high-pressure H2.
