Vibrational spectra, assignments and normal coordinate calculation of acrylamide

The infrared spectra, low temperature infrared spectra, polarized infrared spectra and Raman spectra of acrylamide have been recorded and observed frequencies were assigned to various modes of vibrations on the basis of normal coordinate analysis, assuming Cs point group symmetry. The potential energy distribution associated with normal modes is also reported. The assignment of fundamental vibrations agrees well with the calculated frequencies.
