The atomic component information in turn comprises atomic data and bond data, wherein the atomic data comprises: identification data for identifying the atom forming the atomic component; the coordinate of the foregoing atom; the number of the orbitals associated to the atom; and the coordinate showing the position of free end of the orbital included in the atomic component. Bond data comprises: identification data for identifying the atom that is bonded to the free end of the orbital in the atomic component; identification data for identifying the orbital associated with the atom that is bonded to the foregoing free end; and identification data for identifying the bond order of a bond that is established between the atom forming said atomic component and the atom that is attached to the free end.Other References
