Determination of the parameters of molecular motion from the amplitude spectrum of a spin-echo signal

The amplitude spectrum of the harmonics of a spin-echo signal is determined. The possibilities of obtaining information about the parameters of molecular motion of nuclear spin systems from the spectrum are discussed.Translated from Izvestiya Vyssikh Uchebnykh Zavedenii, Fizika, No. 12, pp. 13–16, December, 1984.
