Further Evidence for Resonant Photoelectron−Solvent Scattering in Nitrous Oxide Cluster Anions

Abstract: The effects of anion solvation by N(2)O on photoelectron angular distributions are revisited in light of new photoelectron imaging results for the NO(-)(N(2)O)(n), n = 0-4 cluster anions at 266 nm. The new observations are examined in the context of the previous studies of O(-) and NO(-) anions solvated in the gas phase by nitrous oxide [Pichugin; et al. J. Chem. Phys. et al. 2008, 129, 044311.; Velarde; et al. J. Chem. Phys. et al. 2007, 127, 084302.]. The photoelectron angular distributions collected in the … Show more

“…There, the PAD of the b 1 −1 channel, yielding 1 A 1 neutral carbene, is perpendicular (β < 0), characteristic of moderate-energy photodetachment from a p-like state (as, for example, in O − and I − photodetachment [26][27][28][29][30][31] − data falling closer to s and NH 2 − to p. The remainder of this paper develops a model description of these trends.…”

“…A common criticism concerning the use of the Wigner law proportionality over energy ranges spanning several electron volts is that the law, being a threshold law, is strictly valid only at vanishingly small kinetic energies (57,(60)(61)(62). However, decades of successful and diverse applications of Hanstorp et al's approach suggest that, although the Wigner law predictions of partial-wave cross sections are not accurate outside the threshold regime, the law's predictions of cross-section ratios are more robust (14,15,24,38,47,74,(79)(80)(81)(82)(83)(84)(85)(86)(87)(88)(89). A more detailed discussion of the range of validity of Wigner partial-wave ratios can be found in the online supplement to Reference 52.…”
