Negative ion photoelectron spectroscopy of cobalt tricarbonylnitrosyl
Photoelectron spectra are reported for the Co(CO)₃NO⁻ and Co(CO)₂NO⁻ anions produced from cobalt tricarbonylnitrosyl in a pulsed valve source. The 355 nm spectra were obtained at a calculated electronic kinetic energy resolution of 96 meV using a newly constructed fixed-frequency negative ion …

Multiphoton ionization photoelectron spectroscopy of iodine-bearing molecules
… by observing the kinetic energy of the ejected photoelectrons. These experiments have demonstrated that, for photoionization of I$\sb2$, CF$\sb3$I and HI at 532 nm, the scission of the R-I bond (R=I, CF$\sb3$, HI) is favored over direct ionization of the molecule at intensities in the range of …

Vibrational and anion photoelectron spectroscopy of transition metal clusters
… anion (TaN−). The data is obtained through anion photoelectron spectroscopy via velocity map imaging (VMI), which permits the simultaneous measurement of photoelectron spectra and photoelectron angular distributions (PADs). The study on TaN− reports the first photoelectron spectra of this diatomic …
