Abstract: A multiply-tuned probe for magnetic resonance imaging or spectroscopy in which a driving inductor is separately coupled to two or more trap inductors. The impedance match at each frequency is adjusted independently of the impedance match at the other frequencies and independent of the tuning by using a novel coil geometry with no overcoupling. In a preferred embodiment, a triple-tuned probe has a first inductor L.sub.1 disposed in a first plane and tuned to a first resonant frequency and a second inductor L.sub.2 disposed in a second plane parallel to the first plane and tuned to a second resonant frequency. A driving and receiving primary inductor L.sub.p is disposed in a third plane parallel to the first and second planes and placed with respect to the first and second inductors L.sub.1 and L.sub.2 such that mutual inductance between L.sub.1 and L.sub.p in between L.sub.2 and L.sub.p is adjustable in accordance with the positions of the inductors L.sub.1, L.sub.2 and L.sub.p.
