Abstract
IN the past few years, several workers have shown1–5 that infra-red spectra can be presented continuously on a cathode ray tube. The presentation of spectra in this way, in scan times as short as several milliseconds, appears to lend itself to the study of rapid chemical reactions and other transient phenomena. In such an investigation of liquid phase reactions, I encountered difficulty in interpreting spectra owing to frequent superposition of bands of the several molecular species involved. To minimize this difficulty, a spectrometer has been designed in which, by a time-sharing double-beam system, spectra giving the percentage difference in absorption between two liquid samples can be displayed as an apparently steady trace on a cathode ray tube.
