Özet

This work deals with the successful spectroscopic properties (infrared, Nuclear magnetic resonance and UV-Vis) and theoretical calculations of chromone and some 6-halogen substituted chromone [C9O2H5X (X: F, Cl and Br)] molecules, namely Chromone (Chr), 6-Fluorochromone (6-Flchr), 6-Chlorochromone (6-Clchr), 6-Bromochromone (6-Brchr). The analysis of the infrared, NMR and UV-Vis spectra of chromone and some halogen substituted chromone molecules, supported by DFT calculations, for the first time has afforded the opportunity to characterize unambiguously the main vibrational bands for these important molecules.
