Single organic dye molecules in the solid state offer a promising platform for quantum technology because of their strong zero-phonon transitions. Coherent access to vibronic states of these molecules has so far not been considered in this context due to their fast relaxation rates. We now report on experimentally observed coherent splitting of a vibronic level obtained by tuning a strong laser beam to the transition between two vibronic states. The experiments were performed with a single dibenzoterrylene molecule in a para-dichlorobenzene crystals at * < 100 mK. In this scheme, the resulting non-Lorentzian resonance profiles can be described only by accounting for the coherent evolution of the density matrix elements.
