Resonance-enhanced multiphoton ionization REMPI and photoelectron spectroscopy PES , have
been used to study the 1
Ag(3d ) Rydberg state of 1,3-trans-butadiene in the two photon energy
range from 61 000 to 66 400 cm 1
. The 1
Ag(3d ) spectrum is dominated by the 4 , 6 , and 9
vibrational modes, with some excitation of the 8 mode, as well. Photoelectron spectroscopy shows
that the dominant ionization pathways are diagonal, i.e., they produce cations in the same vibrational
level that was populated in the Rydberg state. Weaker off-diagonal ionization is also observed, with
excitation of the 4 , 6 , and 9 modes. The relative intensities of diagonal and off-diagonal PES
bands are observed to be strongly dependent on the angle between the laser polarization and the
detection axis. It is possible to use REMPI to generate state-selected cations, however, the nascent
ions are quite efficiently photodissociated by the REMPI laser. 2001 American Institute of
