High-resolution lamellar-grating Fourier-transform spectrometer for the suhmillimeter region

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 H(2)O, CO, N(2)O, and CH(3)CN gases, and, in addition, the magnetic resonance measurements of some biological substances and the refractive index measurements of some III-V compounds are presented.
