title: Symmetry properties of rovibronic states of an X(3) molecule in an upright conical potential.
abstract: The rovibronic structure of cone states of an X3 type molecule is investigated to provide a detailed understanding of the effect of the geometrical phase. When compared to the rovibronic structure of a system in which no geometrical effect is present, a dramatic duplication of the number of rotational levels (k not equal 0) is observed for certain vibrational states (l=0) including the vibrational ground state. Rotational structure may serve as a diagnostic tool to detect the presence of a conical intersection.
