We studied rotational distributions of excited CN ejected due to electron- and photon-stimulated desorption (ESD and PSD) from alkali-metal and alkali-halide surfaces. Measured rotational spectra exhibit temperature-independent non-Boltzmann features that are systematically correlated to the particular alkali-metal component present on the surface. The temperature-independent, substrate-dependent rotational distributions indicate that the molecular rotation following ESD and PSD is determined by direct electronic bond breaking
