    "abstract": "We present an analytic theory for the optical properties of ellipsoidal\nplasmonic particles covered by anisotropic molecular layers. The theory is\napplied to the case of a prolate spheroid covered by chromophores oriented\nparallel and perpendicular to the metal surface. For the case that the\nmolecular layer resonance frequency is close to being degenerate with one of\nthe particle plasmon resonances strong hybridization between the two resonances\noccur. Approximate analytic expressions for the hybridized resonance\nfrequencies, their extinction cross section peak heights and widths are\nderived. The strength of the molecular - plasmon interaction is found to be\nstrongly dependent on molecular orientation and suggest that this sensitivity\ncould be the basis for novel nanoparticle based bio/chemo-sensing applications.",
