Abstract: An experimental technology for detecting a hydrogen bond based on an ssNMR technology includes: (1) exciting a 1H nucleus of an RNA sample with a π/2 pulse; (2) applying two π pulses every half rotation period on an X_nucleus of the RNA sample; (3) applying a π pulse on the 1H nucleus of the RNA sample; (4) applying two π pulses every half rotation period on the X nucleus of the RNA sample; (5) applying a 90° pulse on 1H and X atoms of the RNA sample; (6) recording a chemical shift of X in indirect dimension; (7) applying the 90° pulse on the 1H and X nuclei of the RNA sample; (8) repeating steps 2, 3, and 4; and (9) collecting the 1H signal in direct dimension; where X is selected from the group consisting of 15N and 13C.
