Parametric Nuclear Quadrupole Resonance spectroscopy system and method

A system for identifying a material, said system comprising:

• a first transmitter, transmitting an excitation signal to said material, said excitation signal being tuned to a nuclear quadrupole resonance frequency of said material;
• a second transmitter, transmitting a probe signal to said material;
• a receiver receiving probe signal energy from said material, said receiver generating a baseband signal;
• and
• a processor, said processor detecting a change in said baseband signal, said change resulting from said excitation signal.

A system for identifying a material comprising:

• a first transmitter for exciting said material at a nuclear quadrupole resonant frequency of said material;
• a second transmitter for directing a probe signal toward said material;
• a receiver for receiving a reflected probe signal from said material;
• a processor for detecting a change in a property of the reflected signal resulting from said excitation of said material.
