Abstract

Strong coupling at large electron-molecule distances modifies the threshold laws for photodetachment of a molecular anion near a rotational threshold. If the final polar molecule possesses a symmetry axis containing a nonzero component of angular momentum, cross sections of the type

σ \sim k^{x}

with

x < 1

may result for certain ranges of molecular dipoles, depending on the specific rotational threshold considered.
