Program Wien

Procedure. One approach to the problem is to select a value for a that is obviously too small and to increment it iteratively until the equation is satisfied. This is the method of program WIEN, where the initial value of x is taken as 1 (clearly, -E i < 1 as you can show with a hand calculator). 

Change Program QWIEN so that the second term on the right of the line below statement 10 is x instead of x/5. Solve for this new equation. Change the line below statement 10 so that the second term on the left is xj2. Repeat with j/3, xj, etc. Tabulate the values of a and the values of the denominator. Is a a sensitive function of the denominator in the second term of Program WIEN ... 

Var y the size of the increment in a in program statement 10. Tabulate the increment size, the computed result for a , and the calculated Wien constant. Comment on the relationship among the quantities tabulated.

The EFGs for both 69,7 Ga and 14N have been calculated using the WIEN-97 program, and the results compare more favorably with the experimental results than do those from a simple point charge model including Stemheimer antishielding factors (note that the experimental 14N NQCC value used in the comparison was somewhat larger than the accurate value reported above) [52].

Graphical analysis must always precede the statistical analysis. It is imperative to keep short the time elapsed between data acquisition and data analysis, and in most cases, it is advisable to perform the graphical analysis even while the experiment is still in progress. Wien the data clearly define the nature ofthe rate or binding equation, statistical analysis is not needed to do this. Nevertheless, for a definitive work, statistical methods are necessary for parameter estimation as well as for model discrimination (Senear Bolen, 1992). Computer programs are now available for even the most sophisticated problems in enzyme kinetics (see Section 18.2.4). 

In what follows we discuss the results of ab-initio superceU studies of the relar tive stability of different LSM phases [754]. To perform the ab-initio calculations the program packages WIEN-2k [378] and CRYSTAI 03 [23] were used.

The author is very much indebted to the Austrian fund for the promotion of scientific research (Fonds zur Fbrderung der wissenschaftlichen Forschung, Wien) for the support of this work in the course of a national research program on molded plastic articles, project S 3302, and to Mrs. E. Ratajski for offering Fig. 5 from her still unpublished work. He also wishes to express his thanks to Prof. G. Astarita for inviting him to contribute to the meeting on 100 Years of Academic Chemical Engineering .
