Abstract
The infrared transmittance of nitrobenzene has been measured for wavelengths between 0.7 and 12 μ for seven samples ranging in thickness from 2 cm to about 10 μ. Other published information has been used to extend these transmittance spectra to 25 μ. These over-all data are presented as an absorption-coefficient spectrum from 0.7 to 25 μ. In addition, this absorption-coefficient spectrum has been analyzed in terms of Kerr-coefficient information which may be extrapolated from visible and near-infrared data. It is concluded that Kerr-cell modulation of a near-infrared light beam (to 2 μ) is feasible. Kerr-cell modulation in the 2–15 μ region appears to be unfeasible; however, there may be a good possibility of such operation in the 15–25-μ range.
