Method for adjusting an excitation and detection circuit for nuclear magnetic resonance, and circuit adapted for carrying out said method

摘要

A method of adjusting an excitation and detection circuit for nuclear magnetic resonance, the circuit comprising a probe (S) of the type comprising a single coil (L) for transmitting pulses to excite the nuclear spins of a sample immersed in a magnetic field and for detecting a resonance signal from said nuclear spins, said method being characterized by a step of tuning the resonant frequency in reception of said circuit to the Larmor frequency (f0) of the nuclear spins of the atoms that are to be detected. An excitation and detection circuit for nuclear magnetic resonance, said circuit being characterized in that it is adapted to implement an adjustment method as described above.
