Normal coordinate analysis of 2-aminopyridine (2AP) and ND2-pyridine have b
een performed in valance force field approximation. 2AP was taken as planar
because of the low barrier to amino group inversion. The IR absorption int
ensities have been calculated and the electro-optical parameters (EOP) were
fitted to experimental data in order to produce the experimental relative
intensities. The created force field and EOP reproduce the IR spectrum of t
he molecule studied well. (C) 1999 Elsevier Science B.V. All rights reserve
