Abstract

This paper describes a simple and relatively inexpensive modification of the Perkin-Elmer Model 112 spectrometer for use as a grating instrument. The grating spectrometer has been used to 180 cm−1 wavenumbers in single-pass operation and in double-pass use data have been obtained to 260 cm−1. The wavenumber spread at 200 cm−1 was about 1.5 cm−1; this is gratifying in that the original thermocouple detector was used.
