Rapid Estimation of T1 for Quantitative NMR

Quantitative NMR spectroscopy (qNMR) is an essential tool in organic chemistry, with applications including reaction monitoring, mechanistic analysis, and purity determination. Establishing the correct acquisition rate for consecutive qNMR scans requires knowledge of the longitudinal relaxation time constants (T-1) for all of the nuclei being monitored. We report a simple method that is about 10-fold faster than the conventional inversion recovery technique for the estimation of T-1.

Automated summary

qNMR is a crucial tool in organic chemistry, used for reaction monitoring, mechanistic analysis, and purity determination. Knowledge of longitudinal relaxation time constants (T-1) is essential for establishing the correct acquisition rate for consecutive qNMR scans. The reported method for estimating T-1 is approximately 10 times faster than the conventional inversion recovery technique.
