Infrared spectrum and normal coordinate calculations of deuterated acrylamide

Abstract EN

The infrared spectrum of deuterated acrylamide as mull was measured in the range 4000-180 cm'-1 Normal coordinates treatment of deuterated acrylamide was carried out using general quadratic force field, and the force constants were refined by the damped least-squares method.

The potential energy distributions in both general quadratic space and symmetry coordinates are discussed in relation to the mixing of skeletal frequencies for deuterated acrylamide and the nature of the absorption bands.

The vibrational mean amplitudes are also calculated.
