Rotation selection rule
The Laporte rule is a selection rule formally stated as follows: In a centrosymmetric environment, transitions between like atomic orbitals such as s-s, p-p, d-d, or f-f, transitions are forbidden. The Laporte rule (law) applies to electric dipole transitions, so the operator has u symmetry (meaning ungerade, odd). p orbitals also have u symmetry, so the symmetry of the transition mome… WebRotation meaning in Maths can be given based on geometry. Thus, it is defined as the motion of an object around a centre or an axis. Any rotation is considered as a motion of …
