An experimental procedure is presented to measure the absolute photon yield, the percentage probability of emitting a visible photon per reactant molecule consumed, for chemiluminescent reactions under single collision conditions. Using a well-defined metal beam directed into a scattering gas at sub-millitorr pressures, this procedure is applied to the reactions SmN2O, SmF2, BaN2O, and BaNO2 to obtain the photon yields in the 350-800 nm range of 0.18, 5.5, 1.1 and 0.08 respectively, where the estimated uncertainty is about 50.
