Abstract

The FTIR and FT-Raman spectra of 4-Methyl Picolinic acid (4MPA) was recorded in the range 4000-400 cm-1 and 4000-50 cm-1. A normal coordinate analysis was carried out for all the vibrations of this molecule by solving inverse vibrational problem (IVP) using a 74-parameter modified valence force field employing overlay technique. This reproduced 45 observed frequencies of this molecule with an error of 10.23 cm-1 in the zero-order calculations. PED and eigen vectors calculated in the process were used to make unambiguous vibrational assignments of all the fundamentals.
