Vibration Spectra and Molecular Structure VIII. Absorption Spectra of Light and Heavy Phenol and Aniline Vapors

Abstract
The near infra‐red spectra of light and heavy phenol and aniline vapors have been obtained with a rocksalt spectrometer. Comparisons have been made between the spectra of the light compounds as found in various phases, and an interpretation of certain changes occurring in the spectrum of phenol is suggested. The spectra of the heavy compounds have suggested certain assignments, such as the δ (OD) vibration at 913 cm—1 in heavy phenol and the δ (OH) vibration at 1177 cm—1 in light phenol.
