THE INFRARED SPECTRUM OF H2O IN NON-POLAR SOLVENTS
Abstract
The infrared spectrum of H2O in dilute solution in each of two non- polar solvents, carbon tetrachloride and carbon disulfide, was obtained employing a Perkin-Elmer double beam spectrophotometer Model 221 with NaCl prism-grating interchange. The five-centimeter-pathlength liquid absorption cell designed for containing the samples is described, as are the various attempts to dry each solvent. Also discussed is a detailed method for preparing a correction curve for this spectrophotometer. The asymmetric stretching vibration for the isolated H2O molecule in carbon tetrachloride was found at 1/3705 cm; the symmetric stretching vibration was observed at 1/3613 cm. In carbon disulfide these values were 1/3695 cm and 1/3603 cm respectively. An unsuccessful attempt was made to locate the bending vibration of the isolated H2O molecule. Two bands of lesser intensity were obtained at about 1/3800 cm and 1/3540 cm by graphical separation of the absorption spectrum, and possible explanations for these bands were proposed.
