Abstract
The high-L, non-penetrating, Rydberg states of $H_{2}$ can be understood with a physical picture which would be quite inappropriate for low-L states. The structure of high-L states is dominated by long-range, rather than short range, interactions, with inter-series mixing playing only a minor role. These physical ideas are incorporated into the ``polarization model'' which gives a rather successful a-priori theoretical description of such states.1 The most precise experimental studies of high-L structure have been obtained using fast beam microwave/optical methods.2 In separate experiments, both the (0,1)10L states with $4 \leq L \leq 7$, and the (0,1) nL states with $26 \leq n \leq 30$ and $4 \leq L \leq 6$ have been studied with precision of $< 10^{-5} cm^{-1}$. The most recent experimental results obtained with these techniques will be reviewed and compared with the predictions of the polarization model.
