The rainbow structure of rotationally inelastic differential state-to-state cross sections for anisotropic interaction potentials with an attractive well is investigated within the semiclassical infinite order sudden approximation. The typical structural features of the rainbow catastrophes are closely related to the topology of the potential surface. The observed cusped rainbow singularities can be tamed by two-dimensional Airy and Pearcey uniformization techniques.
