Abstract : We report evidence for of a surface lattice phonon with lower energy than its bulk counterpart, by observation of the excitation spectrum of surface exciton fluorescence for uncoated and N2-coated anthracene crystal 001 face. The line-shape of this surface structure and its behaviour on surface coating are an analysed in terms of surface resonant Raman scattering, intrasurface and surface-to-bulk relaxation processes and coupling between the anthracene surface and the N2 film.
