High resolution 13C spectroscopy by Fourier transform NMR. Thiete sulfone

The high resolution ¹³C NMR spectrum of thiete sulfone (obtained without wide-band ¹H decoupling) indicates that ring strain and re-hybridization in this small ring compound are significant. Pulsed-Fourier operation allows rapid determination of spectral parameters. Experimental acquisition time by pulsed NMR without ¹H decoupling is comparable to the experimental time required for swept ¹³C NMR with complete ¹H decoupling.
