Notes:
Asymmetric Fano line profiles have been observed by autoionization for vibrational Rydberg series of naphthalene. Specific vibrational excitation in the Rydberg series was made possible by two-color excitation that excites the corresponding vibration in the intermediate S1 level. An observed series of autoionizing states involving the ν8¯×ν7 vibration was determined to belong to members n=11 to 22 of a Rydberg series having a quantum defect of δ=0.10 and converging to 1537 cm−1 above the adiabatic ionization potential. The line shapes were analyzed in terms of degenerate resonance interference between optically active discrete and continua states. Observed linewidths were as narrow as 6 cm−1 for naphthalene and 3 cm−1 for naphthalene-d8.
