Spectral evidence for generic charge → acceptor interactions in carbamates and esters.

The correlations of the H NMR, C NMR and FT-IR spectral data from the R-O-C[double bond, length as m-dash]O groups in the alkyl carbamates and esters of homologous alcohols reveal R-group-dependent negative charge stabilization at the carbonyl oxygen and their donation to generic acceptors at C of even alkyl alcohols (R), which explains several of their apparently anomalous properties.
