The symmetry of the superconducting order parameter in Bechgaard salts is still unknown, though the triplet pairing is established by NMR data and by large upper critical field H_c2(0)  5 T for both and . Here we start with a low energy effective Hamiltonian and study the temperature dependence of the corresponding H_c2(T)’s. The chiral f-wave superconductors appear to be the most favourable candidates.
