We consider uniqueness and reconstruction of the potentials qj ∊ L1, and of the (separated) boundary condition parameters, from a dense sequence of nodal points for a two-parameter system of Sturm–Liouville equations linked by the eigenvalue pairs (λ, μ). Under the ‘right definiteness’ condition a1(t1)b2(t1) − b1(t1)a2(t2) > 0 for all t1, t2, we show that a single sequence of nodal points for each j = 1, 2, one point for each eigenfunction yjk, k = 1, 2, …, suffices for our purposes.
