Theoretical and experimental IR spectra and assignments of 3-aminopyridine

Abstract

A normal mode analysis was carried out for 3-aminopyridine using force field refinement method together with ab-initio (4-31G(*)) and semiempirical (AMI) quantum chemical calculations. The initial force field parameters of 3-aminopyridine were refined from the corresponding parameters of pyridine molecule. The results indicate a qualitative agreement in normal modes assignments, which are made upon quantum chemical calculations, force field refinement results and one made earlier upon experimental information.
