A Variation of the Compensation Technique in Infrared Spectrophotometry

Volume 13, Number 3 (June 1959) Page 57-59

Manno, R.P.; Paraskevopoulos, N.; Matsuguma, H.J.


A novel variation of the classical method of spectral cancellation used with double-beam infrared spectrophotometers is presented. The technique described involves the simultaneous utilization of both beams of a double-beam spectrophotometer to compare the spectra of chemically related but not identical substances. The results of preliminary studies, and quantitative application of this new technique, are described.
