Abstract
A quadrature probe for nuclear magnetic resonance includes two sets of coils which are combined with an angle of 90.degree. therebetween. Four pieces of outer conductors and two pieces of ring-shaped inner conductors are capacitively coupled to each other through an insulator or an air gap. In the outer conductor(s) in at least one of a set of outer conductors disposed at positions symmetrical with respect to each other so as to form a first coil and a set of outer conductors disposed at positions symmetrical with respect to each other so as to form a second coil, a conductor member(s) for adjustment is attached in parallel to the arm portion(s) in that outer conductor(s) of that set. Alternatively, the arm portion(s) itself in that set is slidably attached to the wing portions in that set.
