ABSOLUTE ABSORPTION INTENSITY AND DISPERSION MEASUREMENTS ON SOME ORGANIC LIQUIDS IN THE INFRARED

The infrared absorption spectra and corresponding dispersion spectra of the following liquids have been measured over the range 4200 to 250 cm** minus **1: cyclo-C//5H//1//0, CH//3 multiplied by (times) NO//2, CH//3 multiplied by (times) CN, CH//2Br//2, CH//2Cl//2, CBrCl//3, CCl//4, C//6H//6, C//6H//5 multiplied by (times) CH//3, C//6H//5Cl, C//6H//5Br, C//6H//5I, and C//6Fe//6. The spectra were measured in the absence of solvent and the results are reported as the real and imaginary components of the complex refractive index (n, k). The experimental technique combines transmission measurements through thin films and attenuated total reflection measurements by a method which has been described previously.
