文摘

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.
