Abstract
A probe for a nuclear magnetic resonance spectrometer having improved sensitivity and efficiency is described, comprising an impedance matched and tuned coaxial transmission network, multiple radio frequency input-output connections, and a single sample coil. Each individual radio frequency input-output connector and its associated capacitive impedance matching and tuning circuitry is remotely disposed from the magnetic field of the spectrometer. Additional radio frequency input-output connectors of lower frequencies may be modularly added and removed from the probe without altering the impedance settings of high frequency connectors already present.
