Deviations of atoms from

The similar values for distances between Np atom and heterocyclic N atoms, 2.617(5) and 2.649(5) A, were found in [Np02(NCS)(Bipy)(H20)2] H2O (15) (Fig. 15), [92]. The Np-NCS distance is shorter and equal to 2.500(5) A. The deviations of atoms from the least-squares equatorial plane range from 0.047 to 0.417 A, with maximum values corresponding to nitrogen atoms of Bipy (0.396 and 0.417 A). Nitrogen atom of NCS ion deviates by 0.246 A. The neptunyl group is tilted to the equatorial plane by the angle of 70.6°. [Pg.385]

In the analysis of crystal growth, one is mainly interested in macroscopic features like crystal morphology and growth rate. Therefore, the time scale in question is rather slower than the time scale of phonon frequencies, and the deviation of atomic positions from the average crystalline lattice position can be neglected. A lattice model gives a sufiicient description for the crystal shapes and growth [3,34,35]. [Pg.858]

Lucretius (Titus Lucretius Caras, 99 BCE - 55 CE) of Rome wrote a poem, De Rerum Natura (On the Nature of Things) (24) in which he described the atomic theory of Epicums of Samos (342-271 BCE). For Epicurus, atoms were indivisible, invisible, and indestmctible, and they differ in size, shape and weight. He believed that a void exists because there can be no motion of the atoms without it. The motions of atoms included the downward motion of free atoms because of their weight, swerve, the deviation of atomic motion from straight downward paths, and blow, which results from collisions and motion in compoimd bodies. Lucretius called atoms poppy seeds, bodies, principals, and shapes (25). [Pg.31]

If the activation energy is fixed at 76.25 kcals, then the resulting pre-exponential factor for the flame data is calculated to be 1.76 x 10, almost identical with Ref. 1. The scatter in the flame data for the narrow temperature range covered has an average deviation of 28% from the value recommended by Ref. 1. While the cause(s) of the scatter are not known, the largest uncertainties are attributable to errors in temperature, 0 atom concentration and small errors in the concentration profiles which are magnified by taking numerical derivatives. [Pg.380]
