Comment on “Calculation of Two-Center Nuclear Attraction Integrals over Integer and Noninteger n-Slater-Type Orbitals in Nonlined-Up Coordinate Systems”

Recently published formulas for the calculation of two-center nuclear attraction integrals (T. Özdoğan, S. Gümüş and M. Kara, J. Math. Chem. 33 (2003) 181) are critically analyzed. It is shown that the analytical relations presented in this work are not original and they can easily be derived by means of a simple algebra from the formulas for overlap integrals, their rotation coefficients and expansion of the product of two normalized associated Legendre functions in elliptical coordinates published in our papers (I.I. Guseinov, J. Phys. B 3 (1970) 1399; Phys. Rev. A 32 (1985) 1864; J. Mol. Struct.: Theochem 336 (1995) 17).
