Calculation of electric multipole moment integrals with the different screening parameters via the Fourier transform method
Yukcu, N.; Senlik, I.; Oztekin, E. (Wiley, 2012)Three-center electric multipole moment integrals over Slater-type orbitals (STOs) can be evaluated by translating the orbitals on one center to the other and reducing the system to an expansion of two-center integrals. ... -
Evaluation of recurrence relationships and numerical solutions for finite rotation matrix elements by using auxiliary functions
Oztekin, E.; Ozcan, S. (Springer, 2008)In this article, we derived several new recurrence relations of the rotation matrix elements by using Gauss' recurrence formulas for hypergeometric functions and auxiliary functions A(m',m)(j)(beta), and B-i,l(k)(beta). ... -
Generating function for rotation matrix elements
Akdemir, S. O.; Oztekin, E. (Wiley-Blackwell, 2012)The rotation matrix elements are expressed in terms of the Jacobi, Hypergeometric, and Legendre polynomials in the literature. In this study, the generating function is presented for rotation matrix elements by using ... -
New analytical expressions, symmetry relations and numerical solutions for the rotational overlap integrals
Akdemir, S. O.; Eryilmaz, S. D.; Oztekin, E. (Wiley-Blackwell, 2012)In this article, extremely simple analytical formulas are obtained for rotational overlap integrals which occur in integrals over two reduced rotation matrix elements. The analytical derivations are based on the properties ... -
Recurrence Relations for Radial Parts of STOs and Evaluation of Overlap Integrals via the Fourier Transform Methods
Ozay, S.; Oztekin, E. (Elsevier Academic Press Inc, 2013)In this paper, new analytical and numerical methods to evaluate overlap integrals of Slater type orbitals (STOs) with the same and different screening parameters and the recurrence relations for STO radial parts via the ... -
Reducing and Solving Electric Multipole Moment Integrals
Yukcu, N.; Oztekin, E. (Elsevier Academic Press Inc, 2013)Electric multipole moment integrals with the same screening parameters are calculated using Slater type orbitals (STOs) translation formulae and the Fourier transform method. First, multipole moment operators which appear ...
