1.Whereas the wavenumber position of a vibrational band, which relates to the corresponding internuclear force constants, is dependent on electronic structure and bonding, the line width contains information £¨²»Í¨Ë³£©about molecular dynamics. 2.In this study, Raman spectra of liquid acetone and its binary mixtures is recorded and analyzed to influence of hydrogen bond formation and study them £¨Óï·¨²»¶Ô£©rigorously in neat acetone as well as in binary mixtures (Acetone+H2O). 3.All calculations using the GAUSSIAN 03 program.£¨¾ä×Ó²»Í¨£© 4.The optimized structures with formation of hydrogen bonds with solvent molecules were £¨²»Í¨Ë³£©obtained as described in foregoing section. 5.The parameter ¡®a¡¯ in Equ(3) is an adjustable parameter which is basically vibrational mode dependent, and also it depends upon the polarizability of the vibrational mode under investigation and thereby also on its contribution to the linewidth.£¨²»Í¨Ë³£© |
