Comment to "Comment on 'Unified treatment for the evaluation of arbitrary multielectron multicenter molecular integrals over Slater-type orbitals with noninteger principal quantum numbers'"

In a recent publication (Telhat Ozdogan, Int. J. Quantum Chem., 92 (2003) 419), we presented a unified algorithm for the evaluation of multicenter multielectron integrals over Slater type orbitals with noninteger principal quantum numbers, using the one center expansion formula for Slater type orbitals with integer principal quantum numbers (E. Oztekin et. all., J. Mol. Struct. Theochem, 544 (2001) 69; I.I. Guseinov et all., Z. Struct. Khim., 23 (1987) 148 (in Russian)). Guseinov in his comment (physics/0510235) on our publication claims that the presented formulae in our paper could be derived from formulae in his papers by simple algebra. We give a brief response to some of his claims wherever scientifically appropriate. We also assert that the comments are not scientifically justified and rhetoric is highly inappropriate. It should be noted also that it is not easy to understand that what Guseinov intends to do by transforming our procedure into his procedure, which we don't evaluate as a development but can be regarded as a nice sound of science.

Comment to Comment on Cartesian expressions for surface and regular solid spherical harmonics using binomial coefficients and its use in the evaluation of multicenter integrals

The comments of Guseinov on our recent paper (Czech. J. Phys., 52 (2002)1297) have been analyzed critically. It is shown that his comments are irrelevant and also unjust. In contrast to his comment, it is proved that the presented formulae in our study are original and obtained independently, not by changing by the summation indices. It should be stressed that our algorithm is not affected from possible instability problems and also can be used in large scale calculations without loss of significant figures. Meanwhile, his comment on the transformation of our formula into his formula proves the correctness of our algorithm and therefore can be regarded as a nice sound of science.

Response to Comment on Electric Multipole Moments for Some First-Row Diatomic Hydride Molecules [Commun. Theor. Phys. 38 (2002) 256]

The comment of Guseinov is irrelevant and also unjust. In contrast to his comment, we show that the obtained electric multipole moment values for some first-row diatomic molecules are original and better than his values (I.I. Guseinov, E. Akin, and A.M. Rzaeva, J. Mol. Struct. (Theochem) 453 (1998) 163) with respect to Hartree-Fock values. Moreover, it must be noted that all the formulas are cited in our paper (M. Orbay and T. Ozdogan, Commun. Theor. Phys. (Beijing, China) 35 (2001) 585) and corrigendum (M. Orbay and T. Ozdogan, Commun. Theor. Phys. (Beijing, China) 37 (2002) 768).

Reply to Comment on Symbolic Calculation of Two-Center Overlap Integrals Over Slater-Type Orbitals

The comments of Guseinov are critically analyzed. Contrary to his comments, it is pointed out that our formula for two-center overlap integrals over Slater type orbitals have been derived independently, not derived from the earlier works of Guseinov by changing the summation indices. Therefore, our algorithm is original, is not affected from possible instability problems and can be used in large scale calculations without loss of significant figures. Meanwhile, it should be stressed that his comment on the transformation of our formula into his formula proves the correctness of our algorithm and therefore can be regarded as a nice sound of science.

Reply to comment on calculation of two-center nuclear attraction integrals over integer and noninteger n-Slater-type orbitals in nonlined-up coordinate systems

The comments of Guseinov on our paper (T. Ozdogan, S. Gumus and M. Kara, J. Math. Chem., 33 (2003) 181) are critically analyzed. Contrary to his comments, it is proved that the expansion formula for the product of two normalized associated Legendre functions in ellipsoidal coordinates and the expressions for two-center nuclear attraction integrals have been obtained independently, by the use of basic mathematical rules, not by changing the summation indices of expansion relationships contained in his articles. Therefore, our algorithm is original, is not affected from possible instability problems and can be used in large-scale calculations without loss of significant figures. Meanwhile, it should be mentioned that his comment on the transformation of our formulae into his formulae proves the correctness of our algorithm and therefore can be regarded as a nice sound of science.
