Using new high-temperature diamond-anvil-cell designs, together with a variety of optical techniques, we have measured the melting curves of N/sub 2/ to 18.0 GPa, O/sub 2/ to 16.3 GPa, and F/sub 2/ 2.5 GPa. One triple point is found on the N/sub 2/ curve and two on the O/sub 2/ curve. A simple ''effective rotation'' model of librational motions in the solid is used to obtain good theoretical fits to the experimental curves.
