Time-resolved photoelectron spectroscopy of the allyl radical: The lifetimes of the ultraviolet bands

The nonradiative decay of the allyl radical excited B 2 A 1 state studied by picosecond time-resolved photoelectron spectroscopy

Time-resolved photoelectron spectroscopy to probe ultrafast charge transfer and electron dynamics in solid surface systems and at metal-molecule interfaces.

Photoelectron spectroscopy (PES) is a versatile tool, which provides insight into electronic structure and dynamics in condensed matter, surfaces, interfaces and molecules. The history of PES is briefly outlined and illustrated by current developments in the field of time-resolved PES. Our group's research is mostly aimed at studying ultrafast processes and associated lifetimes related to elect...

Tetra-s attachment of allyl cyanide on Si„111...-7Ã7

The investigation of allyl cyanide adsorption on Si(111)-737 using high-resolution electron-energy-loss spectroscopy ~HREELS!, x-ray photoelectron spectroscopy ~XPS!, and ultraviolet photoelectron spectroscopy ~UPS! reveals a tetra-s binding mode through two @212#-like cycloaddition reactions. The HREELS spectra of chemisorbed monolayer show the absence of CvC, CwN, and C(sp)uH stretching modes...

Angle-resolved photoemission spectroscopy of liquid water at 29.5 eV

Angle-resolved photoemission spectroscopy of liquid water was performed using extreme ultraviolet radiation at 29.5 eV and a time-of-flight photoelectron spectrometer. SiC/Mg coated mirrors were employed to select the single-order 19th harmonic from laser high harmonics, which provided a constant photon flux for different laser polarizations. The instrument was tested by measuring photoemission...

A simple electron time-of-flight spectrometer for ultrafast vacuum ultraviolet photoelectron spectroscopy of liquid solutions.

We present a simple electron time of flight spectrometer for time resolved photoelectron spectroscopy of liquid samples using a vacuum ultraviolet (VUV) source produced by high-harmonic generation. The field free spectrometer coupled with the time-preserving monochromator for the VUV at the Artemis facility of the Rutherford Appleton Laboratory achieves an energy resolution of 0.65 eV at 40 eV ...
