Penning ionization electron spectroscopy of nitriles

Abstract: tribution would be sharper on single crystal surfaces.Thermal desorption spectra of CO are shown in Figure 7. Only a single peak was observed around 620 K with small exposures.This peak was shifted to lower temperatures with an increase in CO coverage. Above 1 .O langmuir of CO, the desorption spectra show a shoulder at lower temperatures converging to 510 K. These spectra are quite similar to those on Ir(ll0) reported by Taylor et al.*' They have estimated an activation energy for the desorption of 37 kcal/mo… Show more

“…46 If this propensity is transferred to cyanocyclopropane, the IP value for the n N orbital of cyanocyclopropane is estimated to be 12.93-13.88 eV, which corresponds to the observed IP value for band 3 (12.66 eV).…”

“…It is known that the n N band shows large enhancement in PIES. 23, 26,46 (2) Although bands 3 and 4 are overlapped in PIES, the component of band 3 is dominant. Thus the slope parameter, m, for band 3 is estimated to be -0.52, and its negative peak shift is ∆E ) -400 meV.…”

“…22 The electronic ground state configuration of its 20 valence electrons has been determined using photoelectron [23][24][25][26][27][28] and Penning ionization spectroscopies. 29,30 For the outermost valence molecular orbitals it may be represented in the independent particle model as follows:…”

“…Other than signal from the 1-photon cutoff, data presented in the spectrum of AN are exclusively from two photon ionization as the ionization potential in the FC region is greater than that of [1 + 1 ′ ] ionization. 37 Spectra of CrN and MeAN contain both one and two photon signals, with insets showing the two photon regions of the spectra. The two photon ionization intensities in the calculated spectra were given a 1% weight relative to single photon results.…”
