Modeling the vibrational spectrum of 4,4′-diphenylmethane-bis(methyl)carbamate

We present results of ab initio calculations of the structure and vibrational IR spectrum for 4,4′-diphenylmethane-bis(methyl)carbamate (DPMC). Calculations were carried out in the HF/6-311G approximation with subsequent force-field scaling. The calculated characteristics of the vibrational spectrum of DPMC show satisfactory agreement with experimental values, which permits them to be used in spectral and structural analysis
