N.M.R. of monosubstitued benzenes (C6H5X) in a nematic phase (X = SeCl, SnCl3, PCl2, POCl2 or PSC12)

Written by sctunisie no comments

The proton NMR spectra of monosubstitued benzenes C6H5X (X = SeCl, SnCl3, PCl2, POCl2, PSCl2) oriented in the Merck IV nematic phase were analysed. Effect of the substituant X on the geometry was discussed. The determined structures are in good agreement with those found by electron diffraction for phosphorous dichloride phenyl and phosphonic dichloride phenyl.
