Transformation of C2H4, CO2 and C2H6 absorption spectra under condition of nanoconfinement in SiO2/Al2O3 aerogel is presented for the first time. It is shown that integral intensity of confined C2H4 within 5700–6250 cm–1, CO2 within 4760–5160 cm–1 and C2H6 within 2830–3030 cm–1 are respectively by 13.3, 15, and 18 times higher than in free gas.
