Abstract
Zeeman effect investigations for Cl-35 nuclear quadrupole resonance were carried out at room temperature in single crystals of 4, 4' dichloro diphenyl sulphone. Two field gradient Z -directions were observed in this compound for Cl-35 nucleus. The asymmetry parameter of the electric field gradient system is found to be 0.22±0.03. Orientation of the field gradient directions in the crystallographic co-ordinate system were also determined and compared with the results obtained from X-ray and Neutron diffraction data available for this substance. Percentage single, double and ionic bond characters for C-Cl bond were also estimated.
