- The PPP method Yariair. "R-Purr-Yoplc" methcx} is also called the two-one self-consistent field method. Potential energy, and at the same time, the zero-differential overlap approximation of the electric f-repulsion integral appearing in the calculation process is used, and then the self-consistent field iterative method is used to obtain the two molecular orbitals and their corresponding energies. This method can distinguish the single state or the same configuration State, can also distinguish the geometric isomers of the molecule. The calculation of non-alternating hydrocarbons is closer to reality than HNIU. This method is mainly explained by the spectrum of a conjugate plane molecule. [1]
