Oscillation photograph

In Table IV are given data from oscillation photograph No. 1 of sodalite. The crystal used was a cleaved specimen with a cleaved face (110) 2 mm. square. The incident beam traversed angles between 0 and... [Pg.518]

Data from oscillation photographs of bixbyite show a to be a multiple of 4.68 A (Table I). The Polanyi layer-line relation applied to photographs with [4 00] as rotation axis showed that this multiple must be 2, giving a unit with... [Pg.528]

The predicted structure has been verified by the comparison of the observed intensities of reflection for a large number of planes and those calculated with the use of Equation 1. Data for such comparisons for planes (feOO) and (hOl) reflecting on oscillation photographs are given in Tables I and V, and for other planes giving Laue reflections in... [Pg.535]

The Laue data (Table I) contain first-order reflections only from planes with all indices odd. This fact, together with the absence of reflections with mixed indices on oscillation photographs, shows the lattice to be face-centered. Of the two face-centered space groups isomorphous with point group Td, Td and Td, the latter requires that no odd-order reflections occur from planes (khl) with h — lc. The numerous observed... [Pg.543]

Observed and calculated intensities of reflections on two oscillation photographs, one of which is reproduced in Fig. 5, are given in Table III. The first number below each set of indices (hkl) is the visually estimated observed intensity, and the second the intensity calculated by the usual Bade-methode formula with the use of the Pauling-Sherman /0-values1), the Lorentz and polarization factors being included and the temperature factor omitted. No correction for position on the film has been made. It is seen that the agreement is satisfactory for most of the... [Pg.549]

Because of the large number of structures involving several parameters, a rigorous derivation of the atomic arrangement would be difficult. However, it was evident from the oscillation photographs that the... [Pg.579]

On calculating intensities of reflection for these parameter values, it was found that the general agreement with observation for all except the very weak reflections was excellent, as is shown by the data in Table IV for useful reflections from 45° oscillation photographs from (100) with... [Pg.580]

Using data from Laue and oscillation photographs, it is shown that the unit of structure of binnite has a0 = 10.19 = 0.02 A, the space group being T% The unit contains 2 Cu, J e)124s4/S13, with the atomic arrangement... [Pg.583]

In this way the coordinates of all reciprocal lattice points on the zero layer lying within the area ODBECF are directly determined. Fig. 102 shows the results obtained from a 90° oscillation photograph (Plate VIII) of a gypsum crystal set with its c axis inclined 8 ° to the axis of rotation in spite of the limited precision in the determination of", there is no doubt about where to draw the net. If the remaining. [Pg.175]
