This excess excitation energy leads to an increase in the lifetime of singlet excited chlorophyll, increasing the chances of the formation of long-lived chlorophyll triplet states by inter-system crossing.

To counter this problem, one photoprotective mechanism is so-called non-photochemical quenching ( NPQ ), which relies upon the conversion and dissipation of the excess excitation energy into heat.
43.
Increasing indices, m1, m2, etc ., correlate with increasing levels of excitation energy stored in each of the isomeric states ( e . g ., hafnium-178m2 or ).
44.
Such calculations are based on the fact that the linear response function that is, how the electron density changes when the external potential changes has poles at the exact excitation energies of a system.
45.
If one wants to calculate excitation energies ( energy differences between the ground and excited states ) one has to be careful that both states are equally balanced ( e . g ., Multireference configuration interaction ).
46.
"' Cold fission "'or " cold nuclear fission " is defined as involving fission events for which fission fragments have such low excitation energy that no neutrons or gammas are emitted.
47.
The types of state-to-state transitions available to electrons during an Auger event are dependent on several factors, ranging from initial excitation energy to relative interaction rates, yet are often dominated by a few characteristic transitions.
48.
Since a series of pinholes scans an area in parallel each pinhole is allowed to hover over a specific area for a longer amount of time thereby reducing the excitation energy needed to illuminate a sample when compared to laser scanning microscopes.

Uses fluorescent resonance energy transfer ( FRET ) to enhance its automated RT-PCR . In the FRET reaction, a donor and acceptor probe exchange excitation energy when within 1-5 base pairs ( bp ) on the target sequences.

The purple light is only there because the plasma is being pumped to a higher ionization than it would have at equilibrium for its temperature . ( I think the spiral thread around the tube carries RF current to provide the excitation energy ).
