Local mode spectra of inequivalent C-H oscillators in cycloalkanes and cycloalkenes
Journal Article

· J. Phys. Chem.; (United States)
Local mode spectra of cycloalkanes and cycloalkenes are observed by using both gas-phase high overtone and isotopically isolated fundamental spectroscopy. The shapes of the bands reflect the changes in the C-H bonds during the conformational motion. Absorptions by axial- and equatorial-type C-H bonds are resolved in cyclobutane, cyclopentane, cyclopentene, and cyclohexane, and the isotopically isolated fundamentals are close to the frequencies extrapolated from the overtones except for liquid cyclohexane. The equatorial bands are consistently more intense than the axial ones.
