What type of interaction is responsible for spin-orbit coupling?
What type of interaction is responsible for spin-orbit coupling?
Spin–orbit coupling is an effect in addition to the electron–electron repulsion effect. a. It occurs due to the interaction of the magnetic moment generated and the intrinsic moment of the electron. b.
What is spin-orbit coupling how does it help in understanding fine structure of hydrogen spectrum?
When the familiar red spectral line of the hydrogen spectrum is examined at very high resolution, it is found to be a closely-spaced doublet. The small splitting of the spectral line is attributed to an interaction between the electron spin S and the orbital angular momentum L. It is called the spin-orbit interaction.
Why does an electron in a hydrogen atom experience spin-orbit coupling?
An electron has a magnetic moment associated with its intrinsic (internal) spin. Spin-orbit coupling occurs when this interacts with the magnetic field produced by the orbital angular momentum of the electron.
What must we consider to explain fine structure of the spectrum of hydrogen atom?
From the given question, we can deduce that the fine structure of the hydrogen spectrum is explained by spin angular momentum of electrons whereas orbital angular momentum, finite size of nucleus or the presence of neutrons in the nucleus does not explain the fine structure of the hydrogen spectrum.
What is meant by the fine structure in the spectrum of hydrogen and what is its physical origin?
Fine structure is produced when an atom emits light in making the transition from one energy state to another. The split lines, which are called the fine structure of the main lines, arise from the interaction of the orbital motion of an electron with the quantum mechanical “spin” of that electron.
What is spin orbit interaction in spectroscopy?
In quantum physics, the spin–orbit interaction (also called spin–orbit effect or spin–orbit coupling) is a relativistic interaction of a particle’s spin with its motion inside a potential. The spin–orbit interaction is one cause of magnetocrystalline anisotropy and the spin Hall effect.
What is the electron spin of hydrogen?
A hydrogen atom is an atom of the chemical element hydrogen. The electrically neutral atom contains a single positively charged proton and a single negatively charged electron bound to the nucleus by the Coulomb force….Hydrogen atom.

What is the difference between orbital angular momentum and spin angular momentum?
Just as for angular velocity, there are two special types of angular momentum of an object: the spin angular momentum is the angular momentum about the object’s centre of mass, while the orbital angular momentum is the angular momentum about a chosen center of rotation.
What is spin-orbit interaction in spectroscopy?
The small splitting of the spectral line is attributed to an interaction between the electron spin S and the orbital angular momentum L. It is called the spin-orbit interaction . The familiar red H-alpha line of hydrogen is a single line according to the Bohr theory.
What is spin–orbit coupling in hydrogen-like atoms?
Our treatment of spin–orbit coupling in hydrogen-like atoms may be summarized as follows. In its steady-state of motion, the electron revolves around the nucleus in a circular orbit in the xy-plane, with its magnetic dipole-momentμ aligned either parallel or anti-parallel to the z-axis.
What is meant by fine structure of electron spin?
This splitting is called fine structure and was one of the first experimental evidences for electron spin. The small splitting of the spectral line is attributed to an interaction between the electron spin S and the orbital angular momentum L. It is called the spin-orbit interaction.
What is the fine structure of hydrogen according to Bohr?
Hydrogen Fine Structure. The familiar red H-alpha line of hydrogen is a single line according to the Bohr theory. The straight application of the Schrodinger equation to the hydrogen atom gives the same result.
