Atomic Physics: Coupling Scheme (LS & JJ Coupling)

YouTube Video Description In this video, we discuss the Coupling Schemes in Atomic Physics, focusing on LS Coupling (Russell-Saunders Coupling) and JJ Coupling. The lecture explains how angular momenta of electrons combine inside atoms and how these coupling schemes help in understanding atomic energy levels and spectral structures. 📘 Topics Covered: Introduction to Coupling Scheme Orbital Angular Momentum and Spin Angular Momentum LS (Russell-Saunders) Coupling Total Angular Momentum in LS Coupling JJ Coupling Explained Difference between LS and JJ Coupling Applications in Atomic Spectra Selection of Coupling Scheme in Light and Heavy Atoms This video is useful for: B.Sc Physics Students M.Sc Physics Students Competitive Exams (NET, GATE, JAM, NEET-JEE Basics) Atomic Physics learners If you find this lecture helpful, don’t forget to Like, Share, and Subscribe for more Physics lectures and concept-based learning. 🔔 Subscribe for more Physics videos and notes. #atomicphysics #coupling #LSCoupling #JJCoupling #physicslecture #quantumphysics #spectroscopy #angularmomentum #bscphysics #mscphysics #netphysics #jamphysics #physicseducation Edited by R.Shubho & kingshuk Dey Poster banner by R.Shubho
