The ‘super blood wolf Moon’ from space

Abstract

Ab initio RHF/3-21G** and MM+ molecular mechanics method are employed to calculate the structural chemical parameters of molecular nanoparticles of petroleum asphaltenes. It is found that naphtheno-aromatic rings have a non-planar cup-like character. The values of dihedral angles α between the planes of aromatic and naphthene rings, which are calculated by the RHF/3-21G** method, are within 156-163°. The values of dihedral angles α, which were calculated by the molecular mechanics method, are within 156-164°. [ABSTRACT FROM AUTHOR]
