Separated local field NMR spectroscopy by windowless isotropic mixing
2006 (English)In: Chemical Physics Letters, ISSN 0009-2614, E-ISSN 1873-4448, Vol. 419, no 03-jan, 168-173 p.Article in journal (Refereed) Published
Abstract [en]

A new separated local field NMR experiment, designed for accurate measurements of heteronuclear dipolar couplings, is described. The pulse sequence is based on a homonuclear decoupling windowless heteronuclear isotropic mixing approach to achieve the coherent polarization exchange between the z-components of the magnetizations in heteronuclear spin system. This technique suppresses chemical shifts and frequency offset variations irrespective of the dipolar coupling value. The experiment is demonstrated on a columnar liquid. crystal.
