Abstract
WE have recently completed the construction of an infra-red spectrometer, which, by the automatic balancing of two beams of radiation from the same source, is designed to eliminate variations in the spectrum caused by atmospheric absorption, changes in source radiation intensity, and drifts in the electronic amplification. The infra-red absorption spectrum of any chemical compound can thus be recorded directly as percentage of radiation absorbed versus wave-length. If in solution, the solvent can be placed in the other beam, and the absorption due to the compound alone can thus be ascertained.
