Question

Laporte forbidden transitions are in uv region or in ir region

Answer 1

Answer:

Explanation:

The Laporte Rule is a selection rule in electron absorption spectroscopy that applies to centrosymmetric molecules. It says that transitions between states of the same symmetry with respect to inversion are forbidden.

Answer 2

The Selection Rules governing transitions between electronic energy levels of transition metal complexes are:

ΔS = 0 The Spin Rule

Δl = +/- 1 The Orbital Rule (Laporte)

The first rule says that allowed transitions must involve the promotion of electrons without a change in their spin.

The second rule says that if the molecule has a centre of symmetry, transitions within a given set of p or d orbitals (i.e. those which only involve a redistribution of electrons within a given subshell) are forbidden.
