A theory of surface excitons in molecular crystals is presented using the localized perturbation method. Conditions for the existence of surface excitons and the criterion to determine whether surface exciton states lie above or below bulk exciton states are given in terms of the enviromental shift term and the exciton transfer term within the nearest neighbour approximation. It is shown that localization energies of surface excitons are not sensitive to the crystal thickness. Densities of states for bulk and surface exciton states are calculated. The Davydov splitting of surface excitons is also evaluated.
