We investigate mesons containing charm quarks on fine lattices with a−1 = 5 GeV. We use the quenched approximation with the Wilson gauge action at beta = 6.6. For the quarks we use a nonperturbatively O(a) improved Wilson action. We present results for decay constants and give preliminary results for other current matrix elements.
