The infrared absorption spectra of nitrogen dioxide Ross, W. L.


An automatic calibration marker and wavelength scanning drive has been installed on the Perkin-Elmer infrared spectrometer and the precision of this drive was checked under various operating conditions. The optimum reproducibility was found to be 0.03 wave-drive divisions and the reproducibility under normal operating conditions was found to be G.23 wave-drive divisions at the slowest scanning speed, which is six minutes per revolution of the wave-drive drum. The spectrum of nitrogen dioxide has been examined in the NaCl and LiF prism regions and a tentative assignment of the absorption bands has been made.
