What Is Electron Coupling?
The transport of charge via electrons and the transport of excitation energy via excitons are two processes of fundamental importance in diverse areas of research. ET coupling is essentially the interaction of the two molecular orbitals (MOs) where the electron occupancy is changed.

Also question is, what do you mean by JJ coupling?

In spectroscopy: Total orbital angular momentum and total spin angular momentum. A coupling scheme known as jj coupling is sometimes applicable. In this scheme, each electron n is assigned an angular momentum j composed of its orbital angular momentum l and its spin s.

Beside above, what is coupling in atomic physics? In atomic physics, spin-orbit coupling, also known as spin-pairing, describes a weak magnetic interaction, or coupling, of the particle spin and the orbital motion of this particle, e.g. the electron spin and its motion around an atomic nucleus.

Similarly, it is asked, what do you mean by coupling schemes?

In atomic spectroscopy, Russell–Saunders coupling, also known as LS coupling, specifies a coupling scheme of electronic spin- and orbital-angular momenta. The coupling scheme is named after H. N. Russell and F. A. For heavier atoms j-j coupling gives a better approximation for atomic wave function.

What is JJ coupling and LS coupling?

j-j Coupling In light atoms, the interactions between the orbital angular momenta of individual electrons is stronger than the spin-orbit coupling between the spin and orbital angular momenta. These cases are described by "L-S coupling".

What is JJ coupling in chemistry?

A type of coupling occurring between electrons in atoms and nucleons in nuclei, in which the energies associated with the spin-orbit interactions are much higher than the energies associated with electrostatic repulsion. Multiplets of many-electron atoms having a large atomic number are characterized by j-j coupling.

Is JJ coupling?

In jj coupling, the orbital angular momentum, l, and spin, s, of each electron are first coupled to form a total angular momentum, j, for that electron. Notation: lower case for momenta of individual electrons, upper case for combined momenta.
