The evaluation of the electrostatic potential arising from a line latt
ice with an electroneutral basis is formulated as an integral over an
''effective'' potential function. A procedure for the calculation of t
he ''effective'' potential function based on the Euler-MacLaurin summa
tion formula is presented, and compared with Fourier representation an
d Taylor series expansion methods. A recursive scheme for the evaluati
on of the derivatives (of arbitrary order) of the ''effective'' potent
ial based on the Euler-MacLaurin representation is given. Finally, int
egrals involving products of Gaussian type functions and the ''effecti
ve'' potential are evaluated. Such integrals are required in studies o
f the electronic structure of linear periodic polymers if Gaussian bas
is sets are used.
