The excited state decay of the hydrocarbon radicals ethyl, C 2 H 5 ; propargyl, C 3 H 3 ; and benzyl, C 7 H 7 was investigated by femtosecond time-resolved photoionization. Radicals were generated by flash pyrolysis of n-propyl nitrite, propargyl bromide, and toluene, respectively. It is shown that the 2 2 AЈ ͑3s͒ Rydberg state of ethyl excited at 250 nm decays with a time constant of 20 fs. No residual signal was observed at longer delay times. For the 3 2 B 1 state of propargyl excited at 255 nm a slower decay with a time constant 50± 10 fs was determined. The 4 2 B 2 state of benzyl excited at 255 nm decays within 150± 30 fs.

This review discusses low-lying (n ¼ 3) Rydberg electronic states of molecules and radicals, in particular those that result in mixed configurations and participate in non-adiabatic interactions. Rydberg-valence interactions are ubiquitous in molecules and radicals and have important effects on potential energy surface shapes, spectroscopy, and dissociation dynamics. The review emphasises selected properties that are affected by these interactions and illustrates them with several examples, mostly involving free radicals, in which collaboration between experimental and theoretical investigations has been crucial for understanding. Specifically, the cases of substituted methyl, vinyl, and hydroxyalkyl radicals are described, as well as Rydberg states of diazomethane and the ethyl radical. The issue of triple conical intersections is also briefly discussed.

The 3p Rydberg states of acetone and photodissociation of the acetone cation were studied using time-of-flight (TOF) mass spectrometry. The 3p Rydberg state spectroscopy of acetone was investigated with linearly polarized two-photon resonance enhanced multiphoton ionization (REMPI) from 320 to 337 nm. Several new transition bands were observed in the spectra. In addition to the CH 3 COCH 3 + ion, CH 3 CO + and CH 3 + fragments were observed. The laser power dependences suggest that the CH 3 COCH 3 + , CH 3 CO + and CH 3 + ions are produced in three-, four-, and four-photon processes, respectively. Production of CH 3 CO + and CH 3 + involves excitation of the ground state acetone cation by an additional photon and subsequent decomposition of the excited acetone ion. The average translational energies of CH 3 CO + and CH 3 + from dissociation in CH 3 COCH 3 + (X) + hv → CH 3 CO + + CH 3 and CH 3 COCH 3 + (X) + hv → CH 3 + + CH 3 CO, respectively, were derived from the ion TOF peak profiles. acetone, REMPI, photodissociationCitation: Zheng X F, Wu H X, Song Y, et al.
