title: Broadband photophoretic spectroscopy.
abstract: A means for obtaining broadband photophoretic spectra is described. The sensitivity of the technique is found in accordance with radiometric theory to increase markedly with pressure reduction below 1 atm. Noise oscillation induced by radiometric torques is contained through the use of electronic damping. The first broadband spectrum on a single crystallite (approximtely 5 microm) of CdS is presented.
