Let F be the function field of a smooth, geometrically integral curve over a p-adic field with p≠ 2. In this paper we show that if G is an absolutely simple adjoint algebraic group over F of type A n⁎ 2, C n or D n (D 4 non-trialitarian) such that the associated hermitian form has even rank, trivial discriminant (if G is of type A n⁎ 2 or D n) and trivial Clifford invariant (if G is of type D n) then the group of rational equivalence classes, G (F)/R is trivial.
