Abstract: Let $ H\psi=-\psi''+q\psi$, $ \psi(0)=0$, $ \psi'(1)+b\psi(1)=0$ be a selfadjoint Sturm-Liouville operator acting in $ L^2(0,1)$. Let $ \lambda_n(q,b)$ and $ \nu_n(q,b)$ denote its eigenvalues and the so-called norming constants, respectively. A complete characterization of all spectral data $ (\{\lambda_n\}_{n=0}^{+\infty};\{\nu_n\}_{n=0}^{+\infty})$ corresponding to $ (q;b)\in L^2(0,1)\times\mathbb{R}$ is given, together with a similar characterization for fixed $ b$ and a parametrization of isospectral manifolds.
