state

 [stāt]
condition or situation.
alpha state the state of relaxation and peaceful awakefulness associated with prominent alpha brain wave activity.
anxiety state the condition of experiencing undue anxiety, as in anxiety disorders.
excited state the condition of a nucleus, atom, or molecule produced by the addition of energy to the system as the result of absorption of photons or of inelastic collisions with other particles or systems.
ground state the condition of lowest energy of a nucleus, atom, or molecule.
persistent vegetative state a condition of profound nonresponsiveness in the wakeful state caused by brain damage at whatever level and characterized by a nonfunctioning cerebral cortex, the absence of any discernible adaptive response to the external environment, akinesia, mutism, and inability to signal; the electroencephalogram may be isoelectric or show abnormal activity. Vegetative states raise ethical questions regarding appropriate care, use of resources, and allowing a patient to die.
refractory state a condition of subnormal excitability of muscle and nerve following excitation.
resting state the physiologic condition achieved by complete bed rest for at least 1 hour.
steady state dynamic equilibrium.

ex·cit·ed state

the condition of an atom or molecule after absorbing energy, which may be the result of exposure to light, electricity, elevated temperature, or a chemical reaction; such activation may be a necessary prelude to a chemical reaction or to the emission of light.
Synonym(s): activated state

ex·cit·ed state

(ek-sī'tĕd stāt)
The condition of an atom or molecule after absorbing energy, which may be the result of exposure to light, electricity, elevated temperature, or a chemical reaction; such activation may be a necessary prelude to a chemical reaction or to the emission of light.

In this work, the attention has been focused to the spatial electron distribution in the Hydrogen atom, considering the ground state (n = 1) and the first low-lying excited electronic states (n = 2-6).
In another paper [6], half-lifes of excited electronic states of atoms were found to be proton resonance periods, however, a possible interpretation as electron resonance periods has not been attempted yet.
Paper topics here include positional isotope effects for the water tetramer, dynamic breaking and reporting of finite water chains inside carbon nanotubes, a density functional study of Beryllium clusters, interaction of nitric oxide and nitrous oxide dimer with silver clusters, Li and Be clusters, enhancements of fullerene stability from excited electronic states and recent advances in the fusion and fission of atomic clusters.
NIST researchers were the first to apply time-resolved infrared spectroscopy to unambiguously reveal that electron injection from excited electronic states of the dye molecules (e.g., different complexes of Ruthenium) to the [TiO.sub.2] occurs on the femtosecond ([less than][10.sup.-14] s) timescale.
