Abstract: In order to obtain existence criteria for orthogonal instanton bundles on Pn, we provide a bijection between equivalence classes of orthogonal instanton bundles with no global sections and symmetric forms. Using such correspondence we are able to provide explicit examples of orthogonal instanton bundles with no global sections on Pn and prove that every orthogonal instanton bundle with no global sections on Pn and charge c≥ 2 has rank r≤ (n- 1) c. We also prove that when the rank r of the bundles reaches the upper bound, MPnO(c,r), the coarse moduli space of orthogonal instanton bundles with no global sections on Pn, with charge c≥ 2 and rank r, is affine, smooth, reduced and irreducible. Last, we construct Kronecker modules to determine the splitting type of the bundles in MPnO(c,r), whenever is non-empty
