What causes vibrational relaxation?

Vibrational relaxation is when an excited electron gives some of its vibrational energy to another electron in the same or a different molecule, in the form of kinetic energy.

What is the difference between vibrational relaxation and internal conversion?

IVR is the relaxation of an electron within an electronic state from a high vibrational energy level to a lower one. IC is the relaxation of an electron from a higher electronic state to a lower electronic state by emission of heat.

What is vibrational relaxation in fluorescence?

Fluorescence Spectroscopy, Organic Chemistry Applications Subsequent to excitation, the loss of excess vibrational energy, known as vibrational relaxation, takes place in approximately 10âˆ'12 s the excess energy being lost by inelastic collisions with solvent molecules.

What is the energy relaxation process?

Vibrational energy relaxation, or vibrational population relaxation, is a process in which the population distribution of molecules in quantum states of high energy level caused by an external perturbation returns to the Maxwell–Boltzmann distribution.

Why does vibrational relaxation occur?

The excess energy of the excited vibrational mode is transferred to the kinetic modes in the same molecule or to the surrounding molecules. Through this process, the initially excited vibrational mode moves to a vibrational state of a lower energy.

What causes vibrational excitation?

On a molecular level, absorption of terrestrial infrared radiation of the appropriate wavelength corresponding to the energy-level splittings in the molecule causes vibrational–rotational excitation or, in the case of H2O, pure rotational transitions as well.
