High-resolution NMR with resistive and hybrid magnets: Deconvolution using a field-fluctuation signal

Autor: Kiyonori Takegoshi, Kenjiro Hashi, Takahiro Iijima, Tadashi Shimizu, Teruaki Fujito

Publikováno v: Journal of Magnetic Resonance. 184:258-262

A method for compensating effect of field fluctuation is examined to attain high-resolution NMR spectra with resistive and hybrid magnets. In this method, time dependence of electromotive force induced for a pickup coil attached near a sample is meas
