In the p-amino group of the local anesthetics Benzocaine and Procaine of free basis, the pathway of minimum energy was obtained, corresponding to the torsion and inversion motions with a simultaneous change of the tilt angle, using the AM 1 and CNDO/2 semiempirical methods. The optimum geometric parameters and related potential functions were determined. The Raman bands in the 100-600 cm-1 range were recorded and identified.
