vibronic
Adjective
Meaning
vibronic (comparative more vibronic, superlative most vibronic)
(physics) Describing relationships between electronic and vibrational motions or quantum states
Examples
Computers can also predict vibrational spectra and vibronic coupling, but also acquire and Fourier transform Infra-red Data into frequency information.
In centrosymmetric complexes, such as octahedral complexes, d-d transitions are forbidden by the Laporte rule and only occur because of vibronic coupling in which a molecular vibration occurs together with a d-d transition.
The lasing medium in some dye lasers and vibronic solid-state lasers produces optical gain over a wide bandwidth, making a laser possible which can thus generate pulses of light as short as a few femtoseconds (10 −15 s).
In general, the potential energy surfaces are coupled via the vibronic coupling terms.
The coupling terms are called vibronic couplings.
The valence orbitals in lanthanides are almost entirely non-bonding and as such little effective vibronic coupling takes, hence the spectra from f → f transitions are much weaker and narrower than those from d → d transitions.
