Abstract
The construction and performance of a single beam large aperture spectrometer totally enclosed in a vacuum chamber are described. The focal length of the Czerny-Turner monochromator is 90 cm and plane gratings up to 23 cm × 18 cm are used. The grating drive incorporates a Merton nut. With a Golay detector, the resolution achieved is about 0.12 cm−1 at 1000 cm−1, 0.20–0.30 cm−1 in the range 300–27 cm−1. Illustrative spectra of ammonia, water vapor, and glyoxal are given.This publication has 16 references indexed in Scilit:
