Single-photon ionization of SiC in the gas phase: experimental and characterization of SiC.

We report the first experimental observation of single-photon ionization transitions of the SiC radical between 8.0 and 11.0 eV performed on the DESIRS beamline at the SOLEIL synchrotron facility.

Pulsed-ramped-field-ionization zero-kinetic-energy photoelectron spectroscopy: a methodological advance.

A new experimental method has been developed to record photoelectron spectra based on the well-established pulsed-field-ionization zero-kinetic-energy photoelectron spectroscopy technique and inspired by the data treatment employed in slow photoelectron spectroscopy. This method has been successfully applied to two well-known systems: the XΠ( = 0) ← XΣ+g( = 0) and the XΣ( = 2) ← XΠ( = 0) ionizing transitions of CO and NO, respectively. The first results highlight several advantages of our technique such as an improved signal-to-noise ratio without degrading the spectral resolution and a direct field-free energy determination.

VUV photoionization of the CHNC radical: adiabatic ionization energy and cationic vibrational mode wavenumber determinations.

The photoelectron spectroscopy of CHNC (isocyanomethyl) radical species is investigated for the first time between 9.3 and 11.2 eV in the vicinity of the first photoionizing transition XA← X B.
