The individuality of received complexes was proved by X-ray phase analysis (DRON-3.0). Preparative investigation of complexes was made. Infrared spectrums of complexes were made (Uh-20, KBr). It was proved that in the III complex hydroxylamine is coordinated with Fe (II) by oxygen in the form of n-oxyde-o-NH -and in IV - by nitrogen in the form of NH OH. The composition of IV hasn t been proved in dry ruminant because of surplus age of reagent. Tire composition of III responds to formula of [Fe(NH,OH) Cl,]. [Pg.42]

It will be observed that most syntheses yield pyrylium salts in which positions 2,4, and 6 are substituted. Since according to formulas Ib-lc these positions have a partial positive charge, it can readily be understood why electron-donating substituents (hydroxy, alkoxy, alkyl, or aryl) in these positions stabilize the pyrylium salts. Only three pyrylium salts which do not have substituents in either a-position have been reported and few unsubstituted in y or in one a-position they are less stable toward hydrolysis, and in the case of perchlorates they explode more easily, than 2,4,6-trisubstituted compounds. In fact, the former are secondary, the latter tertiary carbonium ions. This fact also explains why the parent compound (1) was prepared only in 1953. [Pg.250]

Studies on substituent effects are scanty. For the five-membered monocyclic nuclei, the relative positions have been compared to the classic ortho, meta, and para positions of benzene derivatives according to formulae 60 and 61. This comparison is based on the assumption... [Pg.348]

As the structure of Eq. (8) shows, the first coefficient for cp -> 0 in the power expansion of this equation is equal to Einstein coefficient (according to formula (9) it is somewhat higher, but not much). [Pg.84]

With the advent of modern high-speed computers, this is not difficult to do for diatomic molecules, and it is the procedure followed when energy level information is available to perform the summation. Similar procedures have been followed for some nonlinear molecules, although as we have noted earlier, Table 10.4 gives reliable values for these molecules under most circumstances. References can be found in the literature to formulas and tables for calculating corrections for selected nonlinear molecules.12... [Pg.564]

The Compton scattering cannot be neglected, but it is independent of molecular structure. Then, fitting experimental data to formulas from gas phase theory, the concentration of excited molecules can be determined. Another problem is that the undulator X-ray spectrum is not strictly monochromatic, but has a slightly asymmetric lineshape extending toward lower energies. This problem may be handled in different ways, for example, by approximating its spectral distribution by its first spectral moment [12]. [Pg.265]

Work from name to formula, using information about polyatomic ions and being careful to build a formula that is electrically neutral. [Pg.147]

In case when the major input into the change of concentration of free carriers is provided by double-ionized oxygen vacancies which is valid at high temperatures the concentration of conductivity electrons is [e] w 2[Vq ], which, recalling expressions (1.121), (1.124) and (1.125) brings us to formula... [Pg.84]

Here Jta(x) denotes the a-th component of the stationary vector x of the Markov chain with transition matrix Q whose elements depend on the monomer mixture composition in microreactor x according to formula (8). To have the set of Eq. (24) closed it is necessary to determine the dependence of x on X in the thermodynamic equilibrium, i.e. to solve the problem of equilibrium partitioning of monomers between microreactors and their environment. This thermodynamic problem has been solved within the framework of the mean-field Flory approximation [48] for copolymerization of any number of monomers and solvents. The dependencies xa=Fa(X)(a=l,...,m) found there in combination with Eqs. (24) constitute a closed set of dynamic equations whose solution permits the determination of the evolution of the composition of macroradical X(Z) with the growth of its length Z, as well as the corresponding change in the monomer mixture composition in the microreactor. [Pg.184]

You cannot tell from a formula how many atoms of each element are present in a given sample of substance, because there might be a little or a lot of the substance present. The formula tells the ratio of atoms of each element to all the others, and the ratio of atoms of each element to formula units as a whole. [Pg.59]

For Markovian block copolymers the formula is valid analogous to formula (Eq. 58), however factor (Q + e)-1 stands instead of the sum over index v. Thus, in the region of angles 6, at which the inequality Q <3C s holds, the angular dependence of the amplitude of scattering 1(6) of a melt of proteinlike heteropolymers turns out to be identical to that of Markovian heteropolymers with e = i. Essentially, this coincidence disappears for the values of angle 6 at which inequality Q fii is not valid. [Pg.164]

When deriving this expression for the average composition distribution, authors of paper [74] entirely neglected its instantaneous constituent, having taken (as is customary in the quantitative theory of radical copolymerization [3,84]) the Dirac delta-function < ( -X) as the instantaneous composition distribution. Its averaging over conversions, denoted hereinafter by angular brackets, leads to formula (Eq. 101). Note, this formula describes the composition distribution only provided copolymer composition falls in the interval between X(0) and X(p). Otherwise, this distribution function vanishes at all values of composition lying outside the above-mentioned interval. [Pg.194]

In an analogous manner, this approach is extensible to treat simultaneously data of multiple isotopic variants of a particular diatomic species such a treatment might be based on apphcation of differences of spectral terms according to formula 19, with empirical parameters and A therein as explained at that point. In such a treatment there is convenience in distributing a factor reduced mass p between vibrational and rotational quanmm numbers, or rather their respective functionals, in the following form, known as mass-reduced quantum numbers [68],... [Pg.269]
