Miscellaneous techniques for infrared prism spectroscopy are described in detail. These include: techniques for cleaving, cutting, and polishing alkali halide crystals for absorption cell windows; construction of absorption cells for liquids and gases, including some suitable for high and low temperatures and one of long path; the measurement of cell thickness; removal of atmospheric absorption; techniques useful for wavelengths above twenty-five microns; formulas for recording inks. A modified source-optical system and a method of calibration adjustment for Perkin-Elmer Model 12 instruments are also discussed.
