An analytical theory of the optical transitions of a molecule bound at the surface of a 4He droplet is developed for the case of a strong softening of the excited-state nearest neighbor dynamics. The optical bandwidth is found to be determined by the zero-point kinetic energy released at the transition. The theory is applied to the triplet-triplet optical transition in Na2 molecule, for which an asymmetric vibronic band with no pronounced zero-phonon line is predicted, in good agreement with the experiment. © 2009 EDP Sciences, SIF, Springer-Verlag.
