Comment on analytical calculation of atomic and molecular electrostatic potentials from the poisson equation

The assumption, by S. Srebrenik, et. al. (Chem. Phys Letters 20(1973) 419) that methods used for the calculation of atomic and molecular electrostatic potentials phi (r) require numerical integrations of the form phi/sub ab/(r) = ∫rho/sub ab/(r')parallelr'- rparallel-1 dν' is stated to be incorrect because, for a Gauss-type-orbital basis, a closed analytical form exists for the integral.
