Abstract

To obtain further information concerning the interaction between Walsh‐orbitols of ‘conjugated’ cyclopropane rings, the photoelectron spectra of the following compounds have been recorded: bicyclo[4.1.0]heptane 1, cis‐ and trans‐tricyclo[5.1.0^3, 5^]octane 2, 3, diademane 4, trans‐pentacyclo[3.3.2.0^2, 9^.0^4, 10^, 0^6, 8^]decan 5 and bicyclo[4.1.0]heptene‐2 6. The first bands in the PE.‐spectra of these compounds have been assigned on the basis of a ZDO HMO‐approximation. For 2 and 4 the value for resonance integral between linked 2p atomic orbitals of two adjacent eclipsed cyclopropane rings is found to be −1.73 eV.

## Abstract Photoelectron spectra of __endo__‐ and __exo__‐cyclopropano‐norbornene ( = __endo__‐ and __exo__‐tricyclo[3.2.1.0^2.4^]octa‐6‐ene) show that a significant homoconjugation exists between the π‐orbital of the double bond and the symmetric __Walsh__‐__es__‐orbital of the cyclopropane ring
