Representative longitudinal R1 relaxation decay curves showing marked deviation from monoexponential decay for uniformly labeled samples. Ribose C1′ R1 relaxation measurements at 25°C for the A-site RNA labeled with A site selectively-labeled ATP and B uniformly 13C/15N-labeled ATP. Ribose C1′ R1 relaxation measurements at 25°C for A-site RNA labeled with C site selectively-labeled GTP and CTP and D uniformly 13C/15N-labeled GTP and CTP
