Double angle rotation

Fig. 3.11. Schematic two-dimension representation of the structure of cristobalite (a crystalline form of Si02) and of vitreous Si02. Si atoms are represented by full circles, oxygen by open circles. A, B and C represent three cases of double possible equilibrium positions for the atoms of the material in the amorphous state A, transversal displacement B, longitudinal displacement C, small-angle rotation of the Si04 tetrahedron. [Pg.83]

For the notations used, see p. 146 and Schwefel Erg.-Bd.3,1980, p. 81. The principal axes are designated a, b (bisecting the bond angle), and c (l molecular plane). OFg is nearly a prolate top The asymmetry parameter x = (2B-A-C)/(A-C) = -0.9303 may be derived from the double-primed rotational constants given below. [Pg.22]
