Abstract
A 15,000 line per inch, 54 cm grating monochromator based on the new mounting was constructed. The entrance and exit slits are fixed; the grating rotates about a vertical axis through the center of the grating and different wavelengths are obtained in good focus over a wide range simply by this rotation of the grating. This mounting is also applicable to infrared region if grating and detector are changed. The absorption coefficients of methane which was measured by using this monochromator will be presented.
