[7] performed ab initio calculations on E[u.sup.3+]-L complexes, which can be used as benchmarks to assess the accuracy of calculations done at a lower level of theory on larger complexes.
In this paper, we investigate first the effect of a number of transition metals including Zr, Hf, Nb, and Ta on the cohesive properties of the bulk [alpha]-phase and a representative GB in Cr alloys using ab initio calculations. Second, we determine the embrittling potency of 4d and 5d transition metals in Cr alloys in the framework of the low alloying additions concept [8, 9].
Our ab initio calculations at very low-density range (0.02-0.09 g/[cm.sup.3] at 350[degrees]C) indicated 0.09-0.25 H-bonds per water molecule.

According to the relative stability, [DELTA]E, it was found that the [C.sup.1] -centered radical is favored over the [C.sup.1], [N.sup.1], and [N.sup.2]-centered ones by 0.73, 21.39, and 21.32 kcal/mol, respectively, employing the MINDO/3 method, The [C.sup.1]-centered radical being favored over the [N.sup.1] and [N.sup.2]-centered radical isomer by 21.39 and 21.32 Kcal/mol respectively is in reasonable agreement with the values of 18.5 and 19.9 kcal/mol reported in other ab initio calculations [14, 15].

Ab initio calculations follow the approximation that the chemical bonds are elastic, but it is not the case especially at higher range of frequencies due to anharmonicity of vibrations [7].

Based on previous ab initio calculations, we predicted that (1) Oz forms a stable base pair with guanine, (2) the Oz:G base pair is planar, and (3) it has two hydrogen bonds (Figure 1) [8-10].
