A recycled flow Fourier transform nuclear magnetic resonance system is evaluated for analytical utility. It is demonstrated to have wide applicability, particularly for the observation of nuclei with long relaxation times or negative nuclear Overhauser effects. Signal to noise improvements of a factor of 2-10 are demonstrated for /sup 13/C, /sup 31/P, /sup 113/Cd, /sup 29/Si, and /sup 15/N NMR spectra of model compounds. The approach is shown to be compatible with the use of immobilized free radicals which reduce required premagnetization volumes and with spectral editing techniques (e.g., distortionless enhancement by polarization transfer (DEPT)). 19 references, 8 figures, 4 tables.
