Abstract
A precision method is described for measuring the wave-lengths of radiation in the near infra-red region of the spectrum using a six-foot Rowland concave grating with a Thalofide cell. The results obtained are believed to be accurate within 0.001μ. With this method the wave-length of an outstanding absorption band of liquid benzene was determined. The frequency of this band together with those of other bands previously measured by the authors substantiate the theory that the absorber of these radiations is a linear anharmonic oscillator, whose energy states are represented by odd multiples of half quanta.
