Abstract

A new approach to the analysis of the Bloch equations is proposed, in which the features of NMR signal registration are considered using time-dependent coefficients. New relationships have been obtained, and the relative errors in determining the time of the first peak of the NMR signal and its amplitude have been calculated. These relationships make it possible to reduce the time required to find the optimal values of magnetic field parameters and modulation frequencies.
