19F multiple region selected 2D NMR correlation experiments

19F multiple region selected 2D NMR correlation experiments. Cheatham, Steve; Groce, John (DuPont Crop Protection, Stine-Haskell Research Center, Newark, DE 19714-0030, USA).In this study， 10493-44-4 and 60838-59-7 are also used. Journal of Fluorine Chemistry, 125(7), 1111-1117 (English) 2004 Elsevier Science B.V. CODEN: JFLCAR. ISSN: 0022-1139. DOCUMENT TYPE: Journal CA Section: 77 (Magnetic Phenomena) The fundamental problem with observation of 19F in many 2D NMR sequences is that the bandwidth over which signals occur (approx. 100 kHz at 376 MHz) greatly exceeds the 90° excitation bandwidth of most liqs. probes. Here we report a method that permits the acquisition of 2D 19F-13C HMQC expts. on compds. that have 19F signals sepd. by many times the actual 90° excitation bandwidth of the probe. The normal observe hard 90° and 180° pulses are replaced with region selected shaped pulses. The shaped pulses are convoluted to include excitation of a narrow region around each 19F signal while leaving the large signal-less regions unexcited. This method produces accurate 90° and 180° pulses on widely sepd. resonances. .
