FTIR and FTR spectral studies of 2-amino-6-bromo-3-formylchromone

摘要

FTIR and FT-Raman spectra of 2-amino-6-bromo-3-formylchromone (ABFC) have been recorded, using Bruker IFS 66V spectrometer. A detailed vibrational spectral analysis carried out and assignments of the observed bands have been proposed on the basis of fundamentals, overtones and combinations, by assuming C-S point group symmetry. A normal coordinate analysis has been performed to characterise the vibrational fundamentals in terms of potential energy distribution (PED). (C) 2003 Published by Elsevier B.V.
