Since Molpro 2022.2 all auxiliary basis sets (e.g. for density fitting or RI) use spherical functions by default, independent of the ''CARTESIAN'' setting. Cartesian auxiliary functions can be used by defining the basis sets in a basis block using, e.g., Since Molpro 2022.2 all auxiliary basis sets (e.g. for density fitting or RI) use spherical functions by default, independent of the ''CARTESIAN'' setting.
