Abstract
“The infrared spectra of cyclopentane, cyclopentene, cyclohexane, eyclohexene, tetrahydropyran, dihydropyran, p-dioxane, trioxane and quinolizidine have been examined in the interval 650 to $5000 cm^{-1}$. Skeletal frequencies from 100 to $250 cm^{-1}$ are observed in combination and difference with the ring stretching fundamental (850 to $1000 cm^{-1}$), with the $C= C$ stretching fundamental and with their overtones. The number of skeletal frequencies is consistent with the symmetry of the molecule.”
