I factor

In this report results of CCF calculations for two mentioned forms of pulses are presented. In these calculations the attenuating coefficient S is replaced by (I-factor of 0)... [Pg.828]

To measure the goodness of fit, and to quantify the structural determination, a reliability (i -factor) comparison is used. In comparing the data and simulation of the experiment for many trial structures, a minimum R factor can be found corresponding to the optimal structure. In this way atomic positions can be determined in favorable cases to within a few hundredths of an A, comparable to the accuracy achieved in Low-Energy Electron Diffraction (LEED). [Pg.507]

Here, i, the van t Hoff i factor, is determined experimentally. In a very dilute solution (less than about 10 3 mol-I. ), when all ions are independent, i = 2 for MX salts such as NaCl, i = 3 for MX2 salts such as CaCl2, and so on. For dilute nonelectrolyte solutions, i =l. The i factor is so unreliable, however that it is best to confine quantitative calculations of freezing-point depression to nonelectrolyte solutions. Even these solutions must be dilute enough to be approximately ideal. [Pg.454]

The i factor can be used to help determine the extent to which a substance is dissociated into ions in solution. For example, in dilute solution, HC1 has an i factor of 1 in toluene and 2 in water. These values suggest that HC1 retains its molecular form in toluene but is fully deprotonated in water. The strength of a weak acid in... [Pg.454]

The same van t Hoff responsible for the i factor showed that the osmotic pressure of a solution is related to the molarity, c, of the solute in the solution ... [Pg.456]

A 1.00% by mass NaCI(aq) solution has a freezing point of —0.593°C. (a) Estimate the van t Hoff i factor from the data, (b) Determine the total molality of all solute species. [Pg.470]

Taking the above mentioned characteristics of the two modes into consideration, we introduced the concept of stereo-control in the enantio-differentiating hydrogenation of various functionalized prochiral ketones on TA-MNi based on the coexistence of 2P and IP on the site of the catalyst. That is the IP function coimteracts the 2P function when IP and 2P coexist, and the relative contribution of the two modes determine the stereochemistry of the product produced in excess and also relates qualitatively to the i factor. [Pg.236]

In some cases spectroscopic evidence for such species exists. Thus the ultraviolet spectrum of acetophenone in aqueous sulfuric acid changes markedly as the concentration of acid is increased.278 In concentrated sulfuric acid simple aldehydes and ketones exists completely in the conjugate acid form. Unsaturated ketones give colored solutions in sulfuric acid and have -factors greater than two. The higher i-factors... [Pg.143]

In 1951 Newman and Deno reported i-factor measurements consistent with the formation of the 2,4,6,a,a-pentamethylbenzyl cation 21 and the heptamethylbenzyl cation 22 in 100% H2SO4. Three U.V. studies... [Pg.338]

Another result of the kinetic analysis of the 3,2- and 1,2,6-hydride shifts which tends to support the claissical view of the ion is the close similarity in the /I-factors in the Arrhenius equation. is 10 for the 3,2-shift and 10 for the 1,2,6-equilibration process. Both factors are roughly normal and might be expected for rearrangements where the rate-determining step is a relatively slow hydride transfer between carbon atoms in the classical ion. [Pg.214]
