Abstract :
We study the enhanced absorption of optical radiation by molecules placed in the vicinity of spherical metal nano-particles in the realistic situation that includes perturbation of the optical field by the absorbing molecules and show that the enhancement is strong only for relatively weak and diluted absorbers.
