Abstract
A probe for nuclear magnetic resonance (NMR) measurement provided with a multiple resonant circuit for detecting signals of two or more nuclides with high detection efficiency for nuclide at low resonant frequency comprises a multiple resonance radio frequency (RF) coil circuit that, with multiple lead lines connected to the RF coil, causes a part of the RF coil, separated by the connection points of the lead lines, to function as the inductor of a trap circuit that cuts off a signal at the frequency Ffor a signal at the resonant frequency Fof a first nuclide and, at the same time, to function as an RF coil that detects a signal at the frequency Ffor a signal at the resonant frequency Fof a second nuclide, thus increasing the signal detection efficiency for the nuclide at the frequency F.
