Webin which the four-component matrix Dirac equation for a spin one-half electron is adapted to a six-component form of the Maxwell equations for a spin-one photon. This version of the Maxwell equations is a direct extension of the Dirac equation for the electron in which two-by-two Pauli matrices are replaced by analogous three-by-three matrices. WebJan 30, 2024 · A Jablonski diagram is basically an energy diagram, arranged with energy on a vertical axis. The energy levels can be quantitatively denoted, but most of these diagrams use energy levels schematically. The rest of the diagram is arranged into columns. Every column usually represents a specific spin multiplicity for a particular species.
