Vibrational Spectra of Fluorinated Aromatics. VII. 1,2,4-Trifluorobenzene

The infrared absorption spectrum of liquid 1,2,4-trifluorobenzene has been obtained in the region 2–38μ with the aid of LiF, NaCl, KBr, and KRS−5 prisms. The Raman spectrum of the liquidh as been photographed with a three-prism glass spectrograph of linear dispersion 15A/mm at 4358A, and depolarization ratios have been measured for the stronger Raman bands. A complete assignment of fundamental vibration frequencies is given, and the spectra are interpreted in detail.
