A novel method for high-resolution ¹H NMR observation of NH moieties in rigid solids has been developed through a collaboration between TIFR Hyderabad, Charles University, and JEOL Ltd. The method is published in "The Journal of Physical Chemistry Letters".
Although NH groups are fundamental in chemistry, their ¹H NMR resolution suffers from ¹H-¹⁴N couplings, which are difficult to decouple. The new method achieves high-resolution spectra by applying a low-power, amplitude-modulated ¹⁴N decoupling scheme at a fast MAS rate of 70 kHz. This research was a joint effort led by TIFR Hyderabad and JEOL Ltd.
