That this is not the case follows from the experimental data discussed by A. Russell (9), and F. Koref (10) has attempted to calculate the change of frequency of an element when it enters into combination by means of the alteration of melting-point and atomic volume. According to Lindemann s equation, for the combined atom ... [Pg.530]

Due to the intermediate coupling the sign of the crystal field matrix element 6 is reversed compared to the pure Russell-Saunders state. Thus for 8-fold cubic coordination a F7 ground state was found. From EPR measurements on Pu3"1" diluted in fluorite host lattices, a magnetic moment at T=0 K can be calculated, ranging from li ff = 1.333 (in Ce02) to y ff = 0.942 (in SrCl2) (24,... [Pg.41]

The hydrodynamic model In this model the adsorbed gas is considered as a liquid film, which can glide along the surface under the influence of a pressure gradient. Gilliland, Boddour and Russel (1958) used this model to calculate their fluxes. [Pg.102]

Chain Termination in the Oxidation of Cumene. Traylor and Russell (35) assume that the acceleration in the rate of oxidation of CH which is produced by added COOH is solely caused by a chain transfer reaction between CO radicals and COOH. This assumption implies that all CH3OO radicals enter into termination via Reaction 13. However, Thomas (32) has found that acetophenone is formed even in the presence of sufficient COOH to raise the oxidation rate of CH to its limiting value. (The receipt of Thomas manuscript prior to publication stimulated the present calculations.) From this fact, and from a study of the acetophenone formed during the AIBN-induced decomposition of COOH, Thomas concludes that the accelerating effect of added COOH is primarily caused... [Pg.33]

Early this year, Middleton and Ingold (29) reported relative rates of chain propagation of a primary, secondary, and tertiary peroxy radical (from allylbenzene, Tetralin, and a-methylstyrene, respectively) with a series of nine hydrocarbons. By using a large excess of one of the first three hydrocarbons, they dealt almost entirely with one chain carrier in each co-oxidation. Relative reactivities were determined by a GLPC method like that of Russell and Williamson (31, 32). They concluded that the average relative reactivities of the primary, secondary, and tertiary peroxy radicals toward the nine hydrocarbons were 5.2/2.2/1.0 but that the relative reactivities of the nine hydrocarbons were about the same toward each type of radical. These results are acceptable as semi-quantitative. However, despite numerous replicate analyses, their experimental method suffers from the same limitations as that of Russell and Williamson, and they give no primary data—only the calculated results. [Pg.54]

Thus, for diethylamine, (7—4 x 10 3 for methylaniline, 13 x 10 3 for pyrrole [1], 44 X 10 3. Combining these figures with appropriate integrated absorption intensities given by Russell and Thompson [5], we may follow Rayliss, Cole and Little [8] in assuming the model of a point dipole in a spherical cavity and calculating the cavity radii. These turn out to be 4-5 (diethylamine), 9 7 (methylaniline) and 9 8 A (pyrrole). [Pg.178]

In general the value of the 0-factor is neither 1 nor 2, but has some other value. In case that the electronic state of the atom is such as to approximate closely to Russell-Saunders coupling the value of the 0-factor can be, calculated in a simple way. The total angular momentum vector of the atom is the resultant of the vector corresponding to... [Pg.58]

The method used in the calculations follows that explained in detail in Ref. [43]. The input quantum defects pa defined with respect to the Russell Saunders coupling scheme, which is the appropriate short-range basis, are given in Ref. 43. At energies corresponding to v = 100 the total number of open and closed channels in the final KF matrix is 414. [Pg.689]

Reduced forms of sulfur, such as sulfide and thiols, also react rapidly with Mn02 (26-28) as well as with FeOx. However, sulfur in fresh water is often present in substoichiometric amounts with respect to iron. Thus little or no free reduced S is present even under strongly anoxic conditions because of the formation of very insoluble FeS x species. Our equilibrium calculations (29) indicate that complexation with reduced sulfur species is not a quantitatively important aspect of Mn speciation in Lake Richard B. Russell (RBR). However, this result does not rule out the occurrence of such species as transient intermediates. [Pg.496]

Fig. 2.54 Neutron reflectivity profile for a symmetric PS-dPMMA diblock (Mw 30 kg moP1) as a function of incident wavevector (Russell 1990). The inset shows the scattering length density (b/V, the neutron scattering length per unit volume) profile normal to the film surface that was used to calculate the reflectivity profile shown as the solid line, This is typical of a block copolymer film containing a multilayer stack, with lamellae parallel to the surface.
