Abstract

A Michelson-type Fourier transform spectrometer has been constructed for high resolution work in the far ir. The instrument has a theoretical resolution of 0.007 cm(-1) and can be used with a tunable band pass filter system for the reduction of sampling points in a specific spectral region. Separations of 0.05 cm(-1) in the inversion spectrum of NH(3) in the 200-cm(-1) spectral region have been observed with about 1000 sampling points and splittings of 0.04 cm(-1) in the NO(2) spectrum at about 100 cm(-1).

摘要

已构建了一台迈克尔逊型傅里叶变换光谱仪，用于远红外区域的高分辨率工作。该仪器的理论分辨率为0.007厘米⁻¹，并且可以与可调谐带通滤波器系统一起使用，以减少特定光谱区域中的采样点。在200厘米⁻¹光谱区域中，用约1000个采样点观测到了NH₃反转光谱中0.05厘米⁻¹的间隔，在约100厘米⁻¹处的NO₂光谱中观测到了0.04厘米⁻¹的分裂。
