The method of the evaluation of the upper and lower bounds of the second-order perturbation of the energy is described. The calculation of upper and lower bounds for the second-order perturbation of the energy in l/Z expansions for two-electron atoms are given.
Hypervirial and Hellmann-Feynman theorems are used to obtain the perturbation energy expansion for the N-dimensional hydrogen atom in an external potential Ar", where a is a positive integer. Coefficients of the energy expansion in A are obtained up to very high order, without explicit knowledge of
Direct ab initio dynamic calculations are performed on the reactions of atomic hydrogen with GeD(n)(CH(3))(4-n) (n = 1-4) over the temperature range 200-2000 K at the PMP4SDTQ/6-311 +G(3df,2p)//MP2/6-31 +G(d) (for n = 2-4) and G2//MP2/6-31 +G(d) (for n = 1) levels. The corresponding k(H)/k(D) ratios
