laporte rule meaning in Hindi

Examples

1. centrosymmetric environment are electric-dipole forbidden by the Laporte rule.
2. :: Laporte rule might work but I still don't see it.
3. Through these research efforts, he discovered what is known in spectroscopy as the Laporte rule.
4. It is relevant, in particular, to the tetrahedral complexes have no center of symmetry so that the Laporte rule does not apply, and have more intense spectra.
5. Molecular symmetry is a fundamental concept in chemistry, as it can predict or explain many of a molecule's spectroscopic transitions ( based on selection rules such as the Laporte rule ).
6. Both can be observed, in spite of the Laporte rule, because the actual transitions are coupled to vibrations that are anti-symmetric and have the same symmetry as the dipole moment operator.
