METHOD AND DEVICE FOR RECORDING TWO-DIMENSIONAL NUCLEAR MAGNETIC RESONANCE SPECTRA

摘要

P TO ELIMINATE THE "CROSSED RAYS" DUE TO A COUPLING BETWEEN CORES AT MOMENTS OF SPIN, IN ORDER TO FACILITATE OR TO ALLOW THE INTERPRETATION OF THE SPECTRUM, CHANGE THE TIME OF MIXTURE T BETWEEN THE SECOND AND THE THIRD IMPULSION OF 90 , STARTING FROM AN INITIAL VALUE T0, PROPORTIONALLY AT THE TIME OF DEVELOPMENT BETWEEN THE FIRST AND SECOND PULSES OF 90 TT0XT, SO THAT, FOR N MEASUREMENTS PROVIDED FOR, THE VARIATION OF THE T-T0 MIXING TIME, WHICH IS SMALLLY REPORTED AT T0, OR A LITTLE EQUAL TO THE PERIOD OF SLIDES OF FREQUENCY RESULTING FROM SCALING OR COHERENT COUPLINGS, AND THE 2D SPECTRUM THUS OBTAINED OBTAINED WITH A SYMMETRICAL TRIANGULATION OR BALANCING ELIMINATING ALL NON-SYMMETRIC RAINS IN RELATION TO THE MAIN DIAGONAL. / The invention is particularly applicable to the study of exchange mechanisms between nuclei of biological macromolecules.
