title: Michelson-type fourier spectrometer for the far infrared.
abstract: This paper describes the construction, performance, and applications of a Michelson-type Fourier spectrometer designed for spectroscopy in the 10-cm(-1) to 200-cm(-1) spectral region. Development of the arc-stabilized mercury lamp, adequate stabilization of the cooled detector, and selection of optimum sampling time have provided reproducible and high S/N interferograms. The evaluated reproducibility and accuracy of intensity of the spectrometer are better than +/-2%. An apodized resolution of 0.1 cm(-1) and accuracy of frequency within +/-0.015 cm(-1) have also been obtained. The electron spin resonance of some biological substances and the refractive index of solids, for example, have been measured with this spectrometer.
