Gyromagnetic resonance spectrometer with spin decoupling

Claim 1

GYROMAGNETIC RESONANCE APPARATUS INCLUDING A MEASUREMENT CHANNEL AND AN OSCILLATOR CHANNEL, SAID MEASUREMENT CHANNEL ADAPTED TO CONTAIN A FIRST GYROMAGNETIC SUBSTANCE AND SAID OSCILLATOR CHANNEL ADAPTED TO CONTAIN A SECOND GYROMAGNETIC SUBSTANCE, MEANS TO PRODUCING A UNIDIRECTIONAL MAGNETIC FIELD FOR POLARIZING SAID SUBSTANCES, MEANS FOR APPLYING DRIVING RADIO FREQUENCY MAGNETIC FIELDS SO SAID SUBSTANCES AT AN ANGLE TO SAID POLARIZING MAGNETIC FIELD TO PRODUCE GYROMAGNETIC RESONANCE IN SAID SUBSTANCES, MEANS FOR MODULATING ONE OF SAID POLARIZING OR RADIO FREQUENCY MAGNETIC FIELDS APPLIED TO EACH OF SAID TWO SUBSTANCES AT A PERIODIC LOW FREQUENCY RATE TO PRODUCE RADIO FREQUENCY SIDE BAND RESONANCE SIGNALS FROM THE SUBSTANCES, THE PARAMETERS OF THE POLARIZING AND RADIO FREQUENCY FIELDS AT EACH SUBSTANCE BEING SO SELECTED THAT RESONANCE AT ONE OF THE SIDE BAND FREQUENCIES IS PRODUCED IN EACH SUBSTANCE, MEANS IN SAID MEASUREMENT CHANNEL FOR DETECTING THE RESONANCE CONDITION IN SAID FIRST SUBSTANCE, SAID OSCILLATOR CHANNEL INCLUDING CIRCUIT MEANS FOR SUPPLYING THE LOW FREQUENCY MODULATION SIGNAL TO SAID POLARIZING OR RADIO FREQUENCY MAGNETIC FIELDS, SAID LOW FREQUENCY MODULATION PRODUCING THE SIDE BAND RESONANCE SIGNALS FROM THE SUBSTANCES, SAID CIRCUIT MEANS INCLUDING MEANS FOR DETECTING SAID SIDE BAND RESONANCE SIGNAL IN SAID SECOND SUBSTANCE TO PRODUCE AN OUTPUT SIGNAL AT SAID LOW FREQUENCY RATE FOR USE BY SAID CIRCUIT MEANS AS SAID LOW FREQUENCY MODULATION SIGNAL, MEANS FOR SELECTIVELY CHANGING THE STRENGTH OF THE DRIVING RADIO FREQUENCY MAGNETIC FIELD APPLIED TO SAID FIRST GYROMAGNETIC SUBSTANCE WHEREBY THE RADIO FREQUENCY FIELD OF INCREASED STRENGTH MAY PRODUCE A SPIN-DECOUPLING EFFECT ON PARTICULAR SECONDARY ATOM PORTIONS IN SAID FIRST SUBSTANCE, AND MEANS OPERATIVE, WHEN THE STRENGTH OF SAID RADIO FREQUENCY MAGNETICV FIELD IS INCREASED, TO APPLY ANOTHER LOW FREQUENCY MODULATION TO SAID FIRST GYROMAGNETIC SUBSTANCE TO PRODUCE A DIFFERNT SIDE BAND GYROMAGNETIC RESONANCE SIGNAL FROM PRIMARY ATOM PORTIONS IN SAID FIRST SUBSTANCE, SAID SIDE BAND RESONANCE SIGNAL FROM THE PRIMARY ATOM PORTIONS BEING DETECTED IN SAID DETECTING MEANS IN THE MEASUREMENT CHANNEL.
