The qualitative features of the four intrashell P states of the boron atom, i. e., the 2 P 0 1 (ground state), 2 P 0 2 , 2 P e 1 and 4 P e 1 states, are investigated. The interelectronic correlation is found to be strongly spindependent. The preference of orientation (relative to the total angular momentum) is found to be explicit. The geometric structures of relevant states and the modes of internal motion are investigated. The decisive effect of quantum mechanical symmetry is emphasized.
