Abstract
The FTIR and FTR spectra of isothiocyanic acid phenyl ester have been recorded in the regions 4000-200 cm-1 and 4000-30 cm-1. The vibrational analysis has been carried out by assuming Cs symmetry. The observed frequencies were assigned to various modes of vibrations on the basis of intensity, frequencies from allied molecules and the normal coordinate calculations. The potential energy distribution associated with normal modes and also reported here. The assignment of fundamental vibrational frequencies for isothiocyanic acid phenyl ester agrees with the calculated frequencies.
