Slow Diffusion by Singlet State NMR Spectroscopy

Small diffusion coeffs. can be measured by using populations of singlet states that have a relaxation time const., Ts, which can be much longer than the longitudinal relaxation time, T1. Spatial information can be encoded with pulsed field gradients in the manner of stimulated echo sequences. Singlet states can be excited via double-quantum coherence to enhance the efficiency of phase encoding and decoding. [on SciFinder (R)]
