We describe the hyperspherical coordinate method and discuss its application to multiply excited states of atoms. A new classification scheme for triply excited states is presented. It is shown that triply excited states exhibit collective modes similar to rotational and vibrational motions of XY3 molecules. We also present a new development of the hyperspherical approach to a four‐electron atomic system.
