The spectrum of fluoroform has been investigated under high resolution (21‐ft. grating) in the photographic infra‐red with an absorbing path of up to 60 meters, obtained by multiple reflection according to the method of J. U. White. In addition, with the same path length the spectrum from 1.2 to 2.4μ was obtained under low resolution with a photoelectric infra‐red spectrometer. A large number of overtone and combination bands, 47 in all, were found. Two parallel bands in the photographic region…
