A single-beam dispersive photothermal beam deflection (PBD) spectrometer system usable in the IR range is described. A Nernst glower along with a severely modified Perkin-Elmer Model 421 monochromator were used to illuminate a solid sample with modulated monochromatic IR radiation. The resulting pho...
