Abstract: The UV Spectra of Me-(SiMe2)-nMe with n = 2,3,4,5,6 have been analyzed by means of the EHMO-CI-SPIN-FREEmethod with four-orbital model. The first and second absorptoin bands arise in essence from the σ→σ* transitions. Furthermore, the contributions of d atomic orbitals in σ and σ* molecular orbitals are discussed in detail.
