Application of Low-Field NMR to the Unambiguous Assignment of Spin-Coupling Parameters. I. Pentafluoro-Iodobenzene
A low-frequency internal-lock spectrometer system, obtained by substitution of a 6.14-MHz rf unit and probe in a Varian HA−100 spectrometer, makes it possible to record high-quality precalibrated 1H and 19F spectra at about 1.5 kG. Since at such field strengths, chemical shifts are reduced by about...
