• Abstract summary: We show that 1H detected 15N-1H heteronuclear multiple-quantum spectroscopy can be carried out at a magic angle spinning frequency of 150 kHz. We also show that the heteronuclear multiple-quantum correlation spectrum can be obtained by shearing the corresponding heteronuclear single-quantum correlation spectrum.

• Abstract: We hereby demonstrate that 1H detected 15N-1H heteronuclear multiple-quantum spectroscopy can be carried out at a magic angle spinning frequency of 150 kHz. While the 15N-1H multiple-quantum coherences can be directly excited from the dipolar order created by the method of adiabatic demagnetization in the rotating frame, it is technically more advantageous to acquire the chemical shift evolution of the heteronuclear multiple-quantum coherence by two separate chemical shift evolution periods for 1H and 15N. We also show that the heteronuclear multiple-quantum correlation spectrum can be obtained by shearing the corresponding heteronuclear single-quantum correlation spectrum.

  We demonstrate that spectra can be acquired at low field using a novel pulse sequence called spin-lock induced crossing (SLIC) This probes energy level crossings induced by a weak spin-locking pulse and produces a unique J-coupling spectrum for most organic molecules. We performed SLIC spectroscopy on a number of small molecules at 276 kHz and 20.8 MHZ, and we show that SLIC spectra can be simulated in good agreement with measurements.
