Description Inspired by recent experiments on quenching kinetics of excited probes in zeolites, we study the site blocking effect on the survival probability of an immobile probe by reaction with mobile reactants. Reactants perform random walks on a diamond lattice under the constraint of prohibiting double occupancy. Reaction takes place when reactants occupy the nearest neighbor sites of the probe. Theoretical expressions are assessed by Monte Carlo simulations. By analyzing the published experimental data with a simple theoretical expression, we show that our model is relevant to the study of the quenching of excited anthracene by nitromethane in dehydrated zeolite Y.
