title: Photoacousttc spectroscopy of vibrational overtones in polyatomic molecules.
abstract: Intracavity gas-phase photoacoustic spectroscopy is used to study the near IR and visible overtone spectra of propylene, 2-butene, 2-methyl-2-butene, 2,3-dimethyl-2-butene, acetone, 2-butanone, and 3-pentanone. The spectra are described in terms of the local-mode theory of vibrations as the absorption of loosely coupled anharmonic C-H oscillators within the molecule.
