Simulations of nuclear magnetic resonance (NMR) experiments can be an important tool for extracting information about molecular structure and optimizing experimental protocols but are often intractable on classical computers for large molecules such as proteins and for protocols such as zero-field NMR. We demonstrate the first quantum simulation of an NMR spectrum, computing the zero-field spectrum of the methyl group of acetonitrile using four qubits of a trapped-ion quantum computer. We reduce...

Two-dimensional NMR lineshape analysis of single, multiple, zero and double quantum correlation experiments
Abstract
NMR spectroscopy provides a powerful approach for the characterisation of chemical exchange and molecular interactions by analysis of series of experiments acquired over the course of a titration measurement. The appearance of NMR resonances undergoing chemical exchange depends on the frequency difference relative to the rate of exchange, and in the case of one-dimensional experiments chemical exchange regimes are well established...

Multiplet-filtered and gradient-selected zero-quantum TROSY experiments for 13C1H3 methyl groups in proteins
Multiplet-filtered and gradient-selected zero-quantum TROSY experiments for 13C1H3 methyl groups in proteins
Abstract Multiplet-filtered and gradient-selected heteronuclear zero-quantum coherence (gsHZQC) TROSY experiments are described for measuring 1Hâ??13C correlations for 13CH3 methyl groups in proteins. These experiments provide improved suppression of undesirable, broad outer components of the heteronuclear zero-quantum multiplet in medium-sized proteins, or in flexible sites of larger proteins, compared to previously described HZQC sequences (Tugarinov et al. in J Am Chem Soc...

Zero-quantum coherence generation and reconversion in magic-angle spinning solid-state NMR is analyzed. Two methods are discussed based on implementations using symmetry-based pulse sequences that utilize either isotropic J couplings or dipolar couplings. In either case, the decoupling of abundant...
