  • Title: Compensation of effect of field instability by reference deconvolution with phase reconstruction.
    Author: Iijima T, Takegoshi K.
    Journal: J Magn Reson; 2008 Mar; 191(1):128-34. PubMed ID: 18248827.
    Abstract:
    A compensation method based on reference deconvolution is developed to obtain high-resolution NMR spectra under an unstable magnetic field. It is shown that the applicability of the original deconvolution method is limited for small fluctuation, and a process what may be called phase reconstruction is proposed to compensate large field fluctuation. We demonstrate the method using a probe with a coil that can generate a fluctuation field artificially. A high-resolution 1H NMR spectrum of ethylbenzene was obtained under the unstable field after compensation with this method.
