Spectral Analysis and Effect of Temperature on Thermodynamic Parameters and Biological Activities of some Substituted Quinoline

The present paper concerns with an introduction of the molecular spectroscopy in brief, selection rule for infrared, Raman spectra and electronic transition. Electronic and vibrational spectra of benzene and quinoline substituents have been discussed. The present paper also concerns the effect of substituents, their position on the vibrational and electronic spectra and the effect of polar and nonpolar solvents have also been discussed. The present investigation also concerns the effect of pH on the vibrational and electronic spectra have also been discussed. The subject also concerns Thermodynamic parameters and biological studies have also been discussed.
