Xenon photoelectron spectrum

The photoelectron spectrum was obtained1 with a Vacuum Generator UV 63 instrument at low resolution (35 eV) using He excitation at 140° and xenon internal calibration. 

Photoelectron spectroscopy has been used to study equilibria in the gas phase. Thus, the taut-omerism of triazoline-5-thione is studied by variable temperature photoelectron spectroscopy <83CJC1197). PhotoeleCtron spectra of 1,2-dimethyltriazoline-5-thione (67a) calibrated with the Pi/2 and Ps/2 lines of argon and xenon are recorded with a resolution of 30 meV. The spectra of freshly evaporated material obtained with a Pj probe indicate the presence of the unchanged thione even at 160 °C. A spectrum recorded with a P2 probe after heating the evaporated sample to 160 °C exhibits an additional minor band at 9.40 eV which is most likely due to 2-methyl-4-methylthiotriazole (67b). 

Figure 5.31 Time correlation spectrum between 4d5/2 photoelectrons and N5-O2 3O2 3 S0 Auger electrons in xenon, recorded with a time-to-digital converter. Note the repetition rate, 208 ns, of the circulating electron bunches in the storage ring. The large second peak contains true and accidental coincidences, and the periodic structure is due to accidental coincidences only. From [KSc93].
