Abstract The dependence of three dimensional numerical integration procedures in spherical polar coordinates on choice of frame of reference is examined for certain molecular integrals. Strong dependence on axial alignment is found for short internuclear distance, and diffuse quadratures, but the results improve significantly for large distances and finer integration grids. The implications of this dependence to invariance against choice of frame of reference are examined in an SCF study on water.
