Electronic structure and photoelectron spectrum assignment of allene
Abstract
In this paper a series of ab initio SCF and configuration calculations were reported for the ground state and excited states X2E, A2E, 2B2 and 2A1 of allene. For ground state X2E Jahn-Teller distorsion was discussed and a twisted angle of 50° and a torsional barriers of 0.21–0.51 eV were derived. Based on calculated results, the experimental photoelectron spectrum of allene has been assigned.
