GATE Physics PYQs 2012–2025 | Rotational Vibrational & Raman Effect | POTENTIALG | Lalit Sir

Описание: #potentialg
In this video, Lalit Sir solves and explains GATE Physics PYQs (2012–2025) from the topic Atomic and Molecular Physics, with special focus on Lasers and Spectroscopy.

This lecture covers both theory + numerical PYQs and is extremely useful for GATE Physics, CSIR NET, JEST, TIFR, and M.Sc / Ph.D entrance preparation.

📚 Topics Covered:
Spectra of one- and many-electron atoms
Spin-orbit interaction
LS and jj coupling schemes
Fine and hyperfine structures
Zeeman and Stark effects
Electric dipole transitions & selection rules
Rotational and vibrational spectra of diatomic molecules
Electronic transitions & Franck–Condon principle
Raman effect
EPR, NMR, ESR spectroscopy
X-ray spectra
Lasers: Einstein coefficients, population inversion, two- and three-level laser systems

All explanations are concept-based, exam-oriented, and fully aligned with GATE Physics PYQs (2012–2025).

👉 This session is part of the Atomic & Molecular Physics series on POTENTIALG by Lalit Sir.
