photoelectron spectra of both sets of molecules were measured. The course of the thermolysis reactions has also been confirmed by mass spectrometric methods and the results of chemical trapping experiments. The assignment of the PE spectral bands for the two series of molecules has been carried out with the aid of time dependent DFT (TD-DFT) and outer valence green’s function (OVGF) calculations. The results
