Sentences with phrase «excitation energy»
"Excitation energy" refers to the energy required to excite or energize something. It is the energy needed to move an object or system from a lower energy state to a higher energy state. Full definition

If the polymers are then exposed to a laser beam, they absorb the light and store it as excitation energy.
Using this method, we were able to determine the colour of the emitted light and finally the extension of excitation energy over the chain - like polymers,» explained Dr. Richard Hildner, who coordinated the research at the University of Bayreuth.
To make the silver particle's plasmon oscillate, more excitation energy is required than for gold.
It arises from a subtle interplay of electronic and nuclear spins: at ultra-low temperatures and corresponding excitation energies, the half - integer total spin of the electronic shell and half - integer total spin of the nucleus are coupled by a very weak hyperfine interaction.
The excitation energy causes the fragmentation, generating atomic energy.
Up to now it had been assumed that the colour of the emitted light depends on how far the excitation energy spreads along the polymers: supposedly, the more bent the polymers were, the smaller the distance over which the energy spread.
The color changes as the excitation energy increases.
The polymers they studied have backbones that are chemically identical and bent to different degrees, but the excitation energy always spreads over the same distance.
In the multiphoton picture the photon character shines through as resonant enhancement in the excitation yield whenever an integer multiple of the photon energy matches the excitation energy of atomic states.
They typically have a characteristic relationship of excitations energy and scattering angle.
For this to work, the organic molecule used for the spacer layer must have an excitation energy higher than those of the donor and acceptor, but such materials are already widely available.
They used a class of nondiffracting beams, known as 2D optical lattices, which spread the excitation energy across the entire field of view while simultaneously eliminating out - of - focus excitation.
In some, as much as 10 per cent of the excitation energy in the form of ultraviolet light is re-emitted as visible light.
By combining first - principles molecular dynamics simulations with state - of - the - art electronic structure methods, the team could predict the excitation energies of the solvents and solutes, such as the ionization potentials of the solvated ions.
Such processes involve chemical reactions, light absorption, formation of excited electronic states, transfer of excitation energy, and transfer of electrons and protons in chemical processes.
The molecules of CO2 become excited, and can lose this excitation energy via radiation of slightly longer wavelength IR in all directions, or by colliding with other molecules.
