Abstract
The combination vibrational bands ν5 + ν9 and ν1 + ν11 of ethylene absorption adsorbed by silica aerogel nanopores of different densities have been studied for the first time in the 5700- to 6300-cm−1 spectral region. The conducted measurements show significant differences between the spectra of ethylene in aerogels and ethylene in the gas phase, which consist of the change of the absorption band shapes, the shift of the band frequency, and the increase of the absorption intensity. It was concluded that in the studied pressure range of 88–952 mbar, the adsorbed ethylene is in the same structural state.
