Atomic And Molecular Spectra Laser By Rajkumar Pdf 56 ❲Plus❳
Dr. Rajkumar’s text often transitions from spectra to Lasers because lasers are a direct application of spectral principles.
Consider a molecule with:
Processes:
Stokes Lines (Inelastic):
Anti-Stokes Lines (Inelastic):
Selection Rules: Not all transitions are allowed. For an atom to absorb or emit a photon, certain quantum mechanical rules must be followed (e.g., $\Delta l = \pm 1$).
