The effect of solvent viscosity on the rate of quenching of naphthalene fluorescence by biacetyl in degassed methylcyclohexane at room temperature has been investigated using pressure to alter the viscosity from 10/sup -2/ poise to about 10 poise. Rates obtained in this work are in good agreement with those of Birks and Leite (J. Phys. B 3, 417 (1970)) who measured the quenching rates in several solvents and solvent mixtures of varying viscosities at atmospheric pressure.
