title: Chemiluminescence of cigarette smoke.
abstract: Chemiluminescence from cigarette smoke (aerosol) and smoke "extracts" (suspensoids) are described. The emissons from aqueous and organic suspensoids persist for hours, are proportional to oxygen solubilities, possess energy of at least 1.8 electron volts, and display characteristics which suggest that the emissions may be partially sensitized by singlet oxygen.
