Multiple Quantum NMR of Partially Aligned Molecules
2006, Annual Reports on NMR SpectroscopyCitation Excerpt :The simplest approach to selective detection of MQ spectra involves phase-cycling in the basic 3–pulse sequence (in Fig. 2) to allow selection of the spectrum of a particular order of coherence. In any spin system, order selective detection of the spectrum of order N is achieved by coadding 4N FIDs at each value of t1 with the phase of the first two pulses incremented from 2π/4N to 2π in steps of 2π/4N with the receiver phase incremented by π/2 at each step (Fig. 6).30–33 Fig. 7 provides an example of the selective detection of the 3–quantum spectrum of the 4–spin system of 3–chloroiodbenzene (2) aligned in nematic liquid crystalline solution.
Multiple-quantum NMR spectra of partially oriented indene: A new approach to estimating order in a nematic phase
2002, Journal of Magnetic ResonanceNovel method of estimating proton-proton dipolar couplings to aid the analyses of NMR spectra of oriented molecules using two-dimensional inverse experiment
2001, Chemical Physics LettersCitation Excerpt :However, one of the major problems of analysis, namely, initial estimation of proton–proton dipolar couplings still persists. Several techniques have been reported in the literature either to simplify the complex spectra or to aid their analysis [9–14]. None of these techniques provide direct estimation of the proton–proton dipolar couplings from the oriented spectra.
