Abstract: The UV Spectra of Ph(SiMe2)nPh with n = 1,2,3,4,5,6 are analyzed by means of the EHMO-CI-SPIN-FREE method with four-orbital models.The first and the second absorption bands arise in essence from the π→π* transitions. Furthermore, the d atomic orbitals of silicon chain, which may play an important role in the red shift of first absoption bands, are discussed.
Key words: Ph(SiMe2)nPh, π→π*transition, EHMO-CI, d(Si) orbitals
