Quantum oscillations in the resistivity (Shubnikov-de Haas effect) at 1.5K and in fields up to 180 KG have been used to characterise the Fermi surface of NbSe 3 . For rotations about the b axis, three frequency branches have been identified. Rotations orthogonal to this axis revealed no new branches.
