We describe the design of a silicon immersion grating spectrograph for the remote detection of chemicals in the atmosphere. The instrument is designed to operate in the two atmospheric windows from 2.3 to 2.5 and 2.8 and 4.2 microns at a resolution o

By exciting NO2 with a narrow band (0.035 cm−1 FWHM) tunable dye laser in the region of 5935 A, an extensive analysis of the K = 0, 1, and 2 subbands of a vibronic transition has been carried out. The analysis of this transition proves that the upp
