| Abstract: | The experimental and theoretically predicted Raman spectra for the first few alkanes in the homologous series: methane, ethane, propane and butane are presented for the region 2700–3100 cm−1. The structure of the spectra is rather complex. Analysis of the results obtained shows that Fermi resonance occurs between the CH stretching vibrations in the 3000 cm−1 region and the 2ν overtones of deformation vibrations in the low frequency (1450–1500 cm−1) region. |
