“…The use of a high resolution NMR spectrometer for recording solid-state phosphorous-31 spectra (1311), pressure dependence of proton chemical shifts (1312), determination of magnetic moments in solution (1313), measurement of frequency separations using a frequency modulated observing field (1314), and resolution enhancement of high resolution NMR spectra of polymers with the aid of a computer (1315) have been considered. The calculation of response in high-resolution experiments (1316) has also been described.…”
