## Abstract The preferred conformations of the methylsulphinyl group in a number of phenyl methyl sulphoxides substituted in the phenyl ring with one, two or three fluorine atoms have been studied by employing a multinuclear NMR approach. From the ^1^H, ^13^C and ^17^O chemical shifts of the methyl
