โœฆ Synopsis

Resonance enhanced multiphoton ionization spectroscopy, (2C1) REMPI, has been employed in jet cooled styrene vapors for the detection of Rydberg states. A resonance appears at 50,484 cm K1 and is interpreted as a 3p)HOMO Rydberg transition (dZ0.52). The 3s state was not detected in the REMPI experiments. The comparison of the experimental spectrum of styrene, in the energy region 5.3-6.6 eV, with two theoretical works from the literature (CASPT2 and SAC-CI) shows that the CASPT2 results are very close to the experiment and more reliable than the SAC-SI.

Two-photon photoacoustic spectra of acetone&, and \_ds have been recorded using a pulsed laser in the 3ptn Rydberg transition region (332.2-338.7 nm for two-photon excitation). Comparison of the acetone-h, and -d6 photoacoustic and twophoton resonance enhanced multiphoton ionization spectra shows an
