Study of the electronic structure of crystalline modifications of carbon by MO LCAO methods. II. Electronic spectrum of the crystalline modification of carbon C2 (4)

The electronic spectrum of the hypothetical modification of carbon C2(4), formed as a result of the regular cross-linking of carbon macromolecules having fourthorder screw axes of different chirality, has been calculated in the one-electron approximation by the MO LCAO method with allowance for the interaction of nearest neighbors. It has been shown that this modification should have a spectrum typical of semiconductors.
