摘要

The synthesis of the heterospirenes 1-9 is described and their He I photoelectron (PE) spectra are recorded. The assignment of the fit PE bands is based on a comparison with fragment molecules and on molecular orbital calculations using semiempirical methods (PPP, MIND0/3). In the case of 1, 2, 4, and 5 strong spirointeraction has been elucidated. For 3 the analysis of the spectrum is hampered due to the strong overlap of bands while for 6 ...
