Abstract:
N-alkyl-o-nitrophenyl carbamates present two absorption bands in the 1700-1800 cm-1 region and similar N-alkyl-p-nitrophenyl carbamates have only one carbonyl stretching vibration band. The modifications which occur in the IR spectra, when certain carbamates crystallize from various solvents by evaporation of the solvent, were studied.
