Rotationally resolved zero-kinetic-energy photoelectron spectrum of nitrogen

zero-kinetic energy photoelectron spectroscopy

where S(t) is the measurement, u f & is the final state, used as a ‘‘screen’’ onto which we project the dynamics, m(Q) is the coordinate dependent dipole coupling and uex(t)& is the evolving state that we wish to study. A range of techniques using different kinds of final states u f & have been implemented: time-resolved fluorescence spectroscopy; ionization/mass spectroscopy; stimulated emissi...

Zero kinetic energy photoelectron spectroscopy of triphenylene.

We report vibrational information of both the first electronically excited state and the ground cationic state of jet-cooled triphenylene via the techniques of resonantly enhanced multiphoton ionization (REMPI) and zero kinetic energy (ZEKE) photoelectron spectroscopy. The first excited electronic state S1 of the neutral molecule is of A1' symmetry and is therefore electric dipole forbidden in ...

Rotationally resolved pulsed field ionization photoelectron bands

We have obtained rotationally resolved pulsed field ionization-photoelectron ~PFI-PE! spectra of O2 in the energy range of 16.0–18.0 eV, covering ionization transitions O2 (a Pu , v 50 – 18,J) ←O2(X Sg , v950,N9). Although these vibrational PFI-PE bands for O21(a Pu , v) have significant overlaps with those for O2 (X Pg) and O2 (A Pu), we have identified all O2 (a Pu , v 50 – 18) bands by simul...

Zero Kinetic Energy Photoelectron Spectroscopy of Benzo[h]quinoline.

We report zero kinetic energy (ZEKE) photoelectron spectroscopy of benzo[h]quinoline (BhQ) via resonantly enhanced multiphoton ionization (REMPI) through the first electronically excited state S1. From the simulated REMPI spectra with and without Herzberg-Teller coupling, we conclude that vibronic coupling plays a minor but observable role in the electronic excitation to the S1 state. We furthe...
