vibronic การใช้

• The spectra of many of these complexes have some vibronic character.
• Resonance Raman spectroscopy involves a kind of vibronic coupling.
• The intensity of allowed vibronic transitions is governed by the Franck Condon principle.
• Vibronic spectra of diatomic molecules in the gas phase have been analyzed in detail.
• The vibronic coupling acts as a perturbation.
• The direct calculation of vibronic couplings is not common due to difficulties associated with its evaluation.
• Evaluation of vibronic couplings is often associated with severe difficulties in mathematical formulation and program implementations.
• In theoretical chemistry, the vibronic coupling is neglected within the Born & ndash; Oppenheimer approximation.
• Vibronic couplings are crucial to the understanding of nonadiabatic processes, especially near points of conical intersections.
• This is called the vibronic Hamiltonian, a portmanteau of " vibrational " and " electronic ".
• This is shown in the middle figure, where the lower dashed line is a vibronic state.
• As all of the involved states are developed from the same orbitals, they manifest similar vibronic couplings.
• The vibronic transition is indicated by a vertical arrow due to the assumption of constant nuclear coordinates during the transition.
• As a result, the algorithms to evaluate vibronic couplings are not yet implemented in many quantum chemistry program suites.
• Later studies on the same anion were also able to account for vibronic transitions involving low-frequency lattice vibrations.
• In electronic spectroscopy, constructing a "'Deslandres table "'is a useful method to assign vibronic transitions.
• A transition in an energy level of an electron in a molecule may be combined with a vibrational transition and called a vibronic transition.
• Vibronic transitions are allowed at the classical turning points because both the momentum and the nuclear coordinates correspond in the two represented energy levels.
• Transitions that occur as a result of an asymmetrical vibration of a molecule are called vibronic transitions, such as those caused by vibronic coupling.
• Transitions that occur as a result of an asymmetrical vibration of a molecule are called vibronic transitions, such as those caused by vibronic coupling.
