The ^19^F spectrum of cisβ1,2βdichlorohexafluorocyclobutane has been fully analysed on the basis of an [ABX]~2~ spin system, with initial treatment at an [AMX]~2~ level. The chemical shift and coupling constants are presented, and the latter are discussed. Some comments are made on the spectrum of the trans isomer.

## Abstract The decomposition of ^15^N~3~F at β20Β°C leads to __cis__β and __trans__β^15^N~2~F~2~. The corresponding ^19^F NMR spectra were analysed as [AX]~2~ systems. ^19^F, ^15^N and ^14^N NMR spectra were simulated using the novel PC program systems DSYMPCD, DCYMPCD and WINβDAISY running under W
Images of the rat head reflecting glucose utilization were obtained using 2-fluoro-2-deoxy-D-glucose (2-FDG) and 19F nuclear magnetic resonance (NMR) imaging. Spatial heterogeneity of glucose utilization in the rat head was clearly demonstrated showing significantly higher glucose utilization in the
