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.

ground state

the normal, inactivated state of an atom from which, on activation, the singlet, triplet, and other excited states are derived.

ground state

(grownd stāt)
The normal, inactivated state of an atom from which, on activation, the singlet, triplet, and other excited states are derived.

ground state

the condition of a molecule when at its lowest energy level.

ground state

(grownd stāt)
The normal, inactivated state of an atom from which, on activation, the singlet, triplet, and other excited states are derived.

It is seen that the increase of the magnetic field does not change the symmetry of the charge distribution in the ground state, providing only the spatial confinement around the donor location without mixing of the ground state with excited states.
The presence of the off-axis donor in circular QR also breaks the central symmetry [C.sub.[infinity]] of the structure, resulting in the localization of the electron in the ground state and the formation of a nonvanishing energy gap between two lowest levels.
The QCD sum rules are modified by including the contribution of the first radial excited states in addition to the ground state. Our predictions on the masses of the first radial excited states baryons are in good agreement with the experimental data.
Two ground state geometries of SP, cis- and trans-SP conformers, respectively, are optimized within 5000 fs dynamic simulation.
Here the neutron and the proton correspond to the ground state of [sup.31]P and [sup.31]S, respectively, whereas energy states of the second line of the table correspond to the four A baryons.
Two Na atoms colliding along the ground state 3[S.sup.2] + 3[S.sup.2] potential can absorb a photon to produce a bound molecule, in our case to vibrational levels with energy near the 3[S.sup.2] + 3[P.sup.2.sub.3/2] asymptote.
However, a remarkable situation is the case when the Hamiltonian manifests rotational symmetry but the ground state manifests a directional order.
However, their ground state is a singlet, in accordance with the "Ovchinnikov rule" [29].
To obtain a ground state initial configuration, the simulation was run at room temperature for 1000 fs starting with a randomly stacked geometry of benzene and ethylene.
If curlA [equivalent to] 0 or A is continuous at 0,wherethe curlA is the N x N skew-symmetric matrix with entries [a.sub.jk] = [[partial derivative].sub.j][A.sub.k] - [[partial derivative].sub.k][A.sub.j], then (1) has a nontrivial ground state solution.
A system will, most of the time, be in its state of least energy, the ground state, just as a ball will bounce down a hill to the bottom.
Rogachev and coworkers [20] performed a series of calculations involving benzene dimers in the ground state, but no studies have been made on the photochemical dimerization of benzene.
