From analysis of the rotational structure in several emission transitions involving higher electronic states of $\mathrm{<mrow\; data-mjx-texclass="ORD">74</mrow>}GeF$, molecular constants have been derived for four additional excited states. These are the $C2\Delta$ and states (previously known from lower dispersion $work1$), and two new Rydberg states, and $H2\Sigma +$, which form a complex near 50 $000cm-1$.
