✦ Synopsis

A frequency-doubled, continuous tunable dye laser has been employed with a bandwidth of 0.5 cm-r.in the C7r to yield high resolution dynamic information about vibronic excited stntcs of naphthalene in the coltisionlzss regiori The results shornstrong variations of lifetimes in the various sequence modes identified in high resolution absorption spcc&. The evidence points to a strong contribution from both Franck-Condon factors as well as symmetry consideration:

Single vlbromc lifetimes of two-photon excited states are measured in the low pressure limit for naphthalene. The twophoton spectrum, besxdes yieldmg new states in S 1, IS also free of the interference from the neghborhood of the Sz , known from one-photon experiments, and hence unperturbed lifetime
