The geometry optimization was carried out
using the initial geometry generated from standard geometrical
parameters of B3LYP method adopting the 6-31G(d,p) and
6e31þþG(d,p) basis sets to characterize all stationary points as
minima. The optimized structural parameters of the compound
Lornoxicam were used for harmonic vibrational frequency calculations
resulting in IR and Raman frequencies together with intensities.
