✦ Synopsis

Comparison of the photoelectron (PE) spectra of tetravinylmethane (1) and trans, trans, -trans-1,2,3,4-tetravinylcyclobutane (2)

indicates that through-bond interaction in 2 is comparable in magnitude to the through-space Spiro interaction in 1. A similar result is obtained by comparison of the UV absorption spectra of 9,9'-spirobi-
