FIZ 456 - Atomic & Molecular Physics

Course Objectives

1 - Calculating, the energy levels, degeneracy, spin and angular momentum, coupling of the momentums, spectrum of the atoms ranging - from hydrogen to many electron atoms, directly or by using approximations.
2 - To investigate the contexture of bonds of molecules and their spectrums.
