WebThe carbonyl stretching absorption is one of the strongest IR absorptions, and is very useful in structure determination as one can determine both the number of carbonyl groups … WebIR Spectroscopy Tutorial: Alkanes The spectra of simple alkanes are characterized by absorptions due to C–Hstretching and bending (the C–C stretching and bending bands are either too weak or of too low a frequency to be detected in IR spectroscopy). In simple alkanes, which have very few bands, each band in the spectrum can be assigned.
