The quenching of the phosphorescence of several polynuclear aromatci hydrocarbons, dissolved in a fluff-like polystyrene matrix, by oxygen and nitric oxide has been investigated. Nitric oxide is a less efficient quencher than oxygen. Although Franck-Condon factors appear to be important in determining the magnitude of the dynamic oxygen quenching constant, experiments with coronene and monomethyl derivatives of 1, 2 benzanthracene indicate that other factors also play a role.
