In its excited state, an electron in the molecule is pushed into a higher atomic orbit. |
|
When electrons in the excited state outnumber electrons in the resting, or ground state, however, population inversion has taken place. |
|
The frequency of light emitted from atoms in an excited state is measured in emission spectroscopy. |
|
Conversely, if a depolarizing process is much slower than the decay of the excited state, little depolarization will occur before emission. |
|
Taken together we may conclude that, in both experiments, we succeeded in inducing a neutral versus a sexually excited state. |
|
Previous attempts to do this have used light to push individual atoms into an excited state. |
|
However, this estimate does not include the dissipation of energy in the excited state due to solvation and vibrational cooling before dumping. |
|
Such a mixing of configurations is present in proteins, where the energy of the excited state is dissipated among many conformational substates. |
|
The transfer of one electron from an electron donor to an excited state of hypericin generates its corresponding semiquinone radical anion. |
|
When a nucleus decays, through the emission of either an alpha or beta particle, the resulting new nucleus is often left in an excited state. |
|
Fig. 4 compares the decay of the excited state for the native trimer and the solubilized monomer. |
|
One would expect that a single tryptophan residue should have only one excited state lifetime. |
|
We say that the excited state is degenerate, i.e., there are three sets of quantum numbers which give the same energy. |
|
In these types of reactions the reactants form intermediates which have electrons in an excited state. |
|
Ground state and electronically excited state molecular properties can now be investigated in more versatile a way. |
|
A mercury lamp, or a mercury vapor lamp, is a gas discharge light using mercury in an excited state to prouce high light output. |
|
When an atom or ion is in its ground state, the electrons spend a lot more time close to the nucleus than they do when the atom is in an excited state. |
|
The transition chosen has also a significant energy difference compared to the energy between the ground state and the first excited state. |
|
The triplet excited state of dyes bound to DNA can serve as probes of slow motions of DNA molecules on timescales of microseconds to milliseconds. |
|
A nucleus can find itself in an excited state when, for example, it has just been created through the disintegration of another radioactive nucleus. |
|
|
The longer lived excited state localized on porphyrin acts as a reservoir for the excited state localized on corrole. |
|
Sodium Lamp A sodium lamp is a gas discharge lamp that uses sodium in an excited state to generate light. |
|
This metastable form is simply the form of the core of Technetium 99, an excited state on a layer of quantum energy. |
|
Enough energy is liberated in the last step to convert the electronic configuration of the luciferase-luciferyl-adenylate complex from a low-energy ground state to a high-energy excited state. |
|
The pulse deposited energy in the electrons of the nucleosides much as sunlight would, putting the nucleosides into an excited state. |
|
As the energy increases further by continued population of the excited state, the negative temperature approaches zero asymptotically. |
|
It is also important to note that photochemical reactions in sunscreens proceed almost exclusively from the triplet excited state reservoir. |
|
In photodissociation, also called photolysis, the absorption of light raises the molecule into an excited state in which one of the chemical bonds no longer exists. |
|
More specifically, phosphorescence is the emission of light from a triplet excited state, where the electron in the ground state and excited state has the same spin orientation. |
|
Delirium is common in the parlance of psychiatry, and excited delirium I'm sure is well known to every doctor in the hospital who has to deal with patients who come in in an excited state. |
|
Detection of the radiation emitted when this excited state decays produces the absorption data. Researchers can use the absorption pattern to determine the atomic bonding configurations of the sample. |
|
The atom is then in an excited state and its momentum is altered. |
|
The nucleus of a metastable isotope is in an excited state and will return to the ground state by emitting a photon in the form of a gamma ray. |
|
The isotopes 65Zn, 71Zn, 77Zn and 78Zn each have only one excited state. |
|
When a ground state molecule absorbs a photon, the values of the electron spins are not altered and thus the primary excited state is the singlet state. |
|
Thus, in a relaxed state the crystals reflect blue and green, but in an excited state the longer wavelengths such as yellow, orange, green, and red are reflected. |
