Nikerov, M. V., D. A. Bochvar, et al. (1982). "MO LCAO study of the electronic structure of crystal modifications of carbon. I. Electron spectra of the C1(41) crystal modification of carbon." Zh. Strukt. Khim. 23: 13-19.

In the single electron approxn. of LCAO MO the electron spectra was calcd of a hypothetical crystal modification of C formed by crosslinked chains of C macromols. with a spiral symmetry 4. The value of the Fermi energy was detd. and the dependence was found of the MO on wave vector along the symmetry direction.
