Abstract: | Overtone spectra of CH and OH stretching vibrations in normal, secondary and tertiary butanol have been studied. A large number of combination and overtone bands, along with the fundamentals have been measured and assigned in the three cases. These data have been used to obtain the vibrational frequency, anharmonicity constant and dissociation energy for the CH and OH stretch motions in the respective molecules. Effect of dilution on the OH fundamental frequency in n-butanol causes a blue shift. |
