Ultrafast <i>T</i>₁-<i>T</i>_1ρ NMR for Correlating Different Motional Regimes of Molecules.

ABSTRACT: Nuclear magnetic resonance (NMR) relaxation times provide detailed information about molecular motions and local chemical environments. Longitudinal T₁ relaxation time is most often sensitive to relatively fast, nano- to picosecond ranges of molecular motion. Rotating frame T_1ρ relaxation time reflects a much slower, micro- to millisecond range of motion, and the motional regime can be tuned by changing spin-lock field strength. Conventional methods for measuring T₁ and T_1ρ relaxation times are time-consuming, since experiments must be repeated many times with incremented magnetization recovery or decay delay. In this work, we introduce two novel and efficient NMR methods to correlate the T₁ and T<
