The sum over S can be carried out analytically by relating the Wigner 6j symbols to the Wigner 9j symbol,... [Pg.576]

The 3 , 6j, and 9j symbols are coupling (transformation) coefficients, defined e.g. in ref. 18 in terms of sums of products of factorials of the quantum numbers. They are best evaluated by computer. [Pg.334]

Fig. ll.l.A lemperature dependence of the vapor pressures of solid H I c04 and of saturated aqueous solution of HTcOj (upper line) open symbols on cooling, lire vapor pressures for solid IlKe04 are represented by the dotted line [9j. [Pg.128]

EXERCISE 9J. Write the electron configuration and the Lewis symbol for Ca and for S... [Pg.337]

higher-order interchanges (Dacre and McWeeny, 1970) that more complicated factors (involving 9j, 12/,. .. symbols) are encountered. [Pg.511]
