Abstract

A lamellar-grating Fourier-transform spectrometer has been constructed for high-resolution studies and for general measurements in the submillimeter region. The instrument has a maximum working resolution of 0.034 cm−1 and an accuracy of frequency of ±0.0015 cm−1. To illustrate the performance of the instrument, the results of high-resolution measurements of H2O, CO, N2O, and CH3CN gases, and, in addition, the magnetic resonance measurements of some biological substances and the refractive index measurements of some III–V compounds are presented.
