Abstract: Theoretical models for the appearance of the third UV continuum in the emission spectrum from nonequilibrium inert gas plasmas are reviewed. A model is proposed which attributes the continuum to transitions from low-lying excited states of the molecular ion that correlate with $R^*(^3P) + R^+(^2P)$ in the low-lying dissociating states of $R_2^+$. The emission efficiency in a beam plasma is $\sim2%$ in accordance with experiment. In a discharge plasma this quantity may be an order of magnitude higher. The features of the continuum in $He, \rm Ne$, and $\rm Ar$, as well as other experimental data, are explained in terms of the model.
