A number of even- and odd-parity levels in ^<19>F are shown to be well explained by an α-^<15>N plus t-^<16>O coupled channel orthogonality condition model. Direct inter-cluster potentials and the coupling potential of α-^<15>N and t-^<16>O channel calculated from a two-body interaction are used with some adjustment for the t-^<16>O potential. Both the α- and t-clusterings are important to understand the structure of ^<19>F. An interesting rule for the coupling between the two cluster states is derived and shown to give an explanation of the large spin-orbit splittings in the t-^<16>O states. Coulomb displacement energies between ^<19>F and ^<19>Ne are also discussed.
