Transformation of C2H4, CO2 and C2H6 absorption spectra confined in nanopores of SiO2/Al2O3 aerogel is studied for the first time in comparison with the spectra of these molecules in the free state. It is shown that the integral intensities of confined C2H4 within 5700–6250 cm–1, CO2 within 4760–5160 cm–1, and C2H6 within 2830–3030 cm–1 are higher by 13.3, 15, and 18 times, respectively, than those of free gases.
