| Abstract: | Time of flight mass spectrometry, electron‐ion coincidence, and ion yield spectroscopy were employed to investigate for the first time the thiazole (C3H3NS) molecule in the gas phase excited by synchrotron radiation in the soft X‐ray domain. Total ion yield (TIY) and photoelectron‐photoion coincidence (PEPICO) spectra were recorded as a function of the photon energy in the vicinity of the carbon K edge (C1s). The C1s resonant transitions as well as the core ionization thresholds have been determined from the profile of TIY spectrum, and the features were discussed. The corresponding partial ion yields were determined from the PEPICO spectra for the cation species produced upon the molecular photodissociation. Additional ab initio calculations have also been performed from where relevant structural and electronic configuration parameters were obtained for this molecule. |
