Wachter

Basch Available for Sc through Cu(15.v8/ 5d) with several contraction schemes. The transition metal set yields slightly higher energy than Wachters set. 

Wachters Available for K through Zn(14.v9/ 5d). Often used for transition metals. 

Some of the basis sets discussed here are used more often than others. The STO—3G set is the most widely used minimal basis set. The Pople sets, particularly, 3—21G, 6—31G, and 6—311G, with the extra functions described previously are widely used for quantitative results, particularly for organic molecules. The correlation consistent sets have been most widely used in recent years for high-accuracy calculations. The CBS and G2 methods are becoming popular for very-high-accuracy results. The Wachters and Hay sets are popular for transition metals. The core potential sets, particularly Hay-Wadt, LANL2DZ, Dolg, and SBKJC, are used for heavy elements, Rb and heavier. 

Duration of Test Although the duration of any test will be determined by the nature and purpose of the test, an excellent procedure for evaluating the effect or time on corrosion of the metal and also on the corrosiveness of the environment in laboratory tests has been presented by Wachter and Treseder [Chem. Eng. Pi og., 315-326 (June 1947)]. This technique is called the planned-interval test. Other procedures that require the removal of sohd corrosion products between exposure periods will not measure accurately the normal changes of corrosion with time. 

The authors are very grateful to P. Wachter for the generous support in providing the access to the technical facilities, and to K. Sattler and D. Ugarte for fruitful discussions, and to J. Muller for technical assistance. One of us (L.D.) wishes to acknowledge the financial support of the Swiss National Foundation for the Scientific Research and of the ETH Research Council.
