| dc.description.abstract | The chromic behavior of a compound is due to photochromism, thermochromisim, electrochromism, solvatochromism, Ionochromism, halochromism, tribichromism and Piezochromism. The term solvatochromism is used to describe changes in Infrared vibrational band followed a change in the polarity of the media. Solvent effects on the vibrational absorption band of nicotinamide in different concentration of binary mixture of solvents were determined. In varying the mole fraction of binary mixture of solvents positive and negative solvatochromism were observed according to the solvation energy of the molecule at the ground states and excited states. The wavenumber functionality on mole fraction were obtained from the correlation graph. Solvent dependent solvation dielectric constant was determined from the correlation plots of wavenumber as the function of dielectric constant mixture of binary solvents as solvent polarity parameter. | en_US |
