The vibrational overtone spectra of aryl and alkyl C-H stretch vibrations in benzaldehyde have been studied using conventional IR and thermal lensing technique at room temperature. The stretching vibrational frequencyωe, anharmonicity constantωexe and the dissociation energies of the two C-H bonds have been calculated. The bond length of C-H bond in aryl position has been estimated.
