Femtosecond time‐resolved ionization reveals the coherent nature of the electronic excitation and relaxation of the S 1 (L b ) and S 2 (L a ) excited states of naphthalene (see picture). The authors describe two different types of coherent behavior: adiabatic evolution, resulting in the transient population of the S 2 state excited out of resonance, and electronic recurrences, observed in the relaxation of this resonantly populated state as a consequence of the strong S 2 /S 1 nonadiabatic coupling.
