Inductive coupling in multiple resonance circuits in a nuclear magnetic resonance probe and methods of use

A Nuclear Magnetic Resonance (NMR) probe comprising:

• a primary circuit including a primary inductor coil with a primary resonance mode located in a first region;
• one or more secondary circuits including one or more secondary inductor coils located in a second region, where the one or more secondary circuits are between:
• a lower limit of approximately 10−3 m;
• and
• an upper limit of approximately 10−1 m from the first region,
• where the one or more secondary inductor coils are electrically connected to the primary inductor coil;
• and
• one or both one or more inductive coupling loops located in the second region inductively coupled to the one or more secondary inductor coils and one or more resonators located in the second region, where at least one of the one or more secondary inductor coils is coupled to the one or more resonators, where the one or more resonators split the primary resonance mode into at least two modes.

A method of detecting coupling modes of a Nuclear Magnetic Resonance (NMR) signal comprising the steps of:

• (A) inductively coupling the NMR probe comprising:
• a primary circuit including a primary inductor coil with a primary resonance mode located in a first region;
• and
• one or more secondary circuits located in a second region where the second region is a distance from the first region including:
• one or more secondary inductor coils, where the one or more secondary inductor coils are electrically connected to the primary inductor coil;
• and
• one or both one or more inductive coupling loops inductively coupled to the one or more secondary inductor coils and one or more resonators, where at least one of the one or more secondary inductor coils is coupled to the one or more resonators, where the one or more resonators split the primary resonance mode into at least two modes;
• and
• (B) adjusting the one or more inductive coupling loops coupling constant (k) to detect one or more of the at least two modes.
