## Abstract Using a modified Extended __HΓΌckel__ (S. C. C.) procedure the structure of the ferrocenylβmethyl cation has been calculated. The result is a structure (V) with about equal overlap population between all Feο£ΏC bonds. The methylene group is bent towards the iron atom and both rings are til

After extraction with CH,CI,, the organic phase was dried (Na,SO,) and purified on silica gel (20 8). After removal of the solvent there remained 0.53 g (72%) of a crystalline product.

The syn dimer of cyclobutadiene (tricyclo[4.2.0.0(2.5)]octa-3,7-diene, TOD) is subjected to ionization under different conditions and the resulting species are probed by optical and ESR spectroscopy. By means of quantum chemical modelling of the potential energy surfaces and the optical spectra, it
