Casimir–Polder forces—dispersion forces between point‐like microscopic particles and macroscopic dielectric bodies caused by ground‐state fluctuations of the electromagnetic field—have long been studied theoretically and experimentally for point‐like particles. In order to describe the interaction of large molecules with typically more than 100 atoms, an extended theoretical concept beyond the point‐dipole assumption is required. Here we develop a formalism to determine the rotationally averaged Casimir–Polder potential on extended rotating molecules.
