Abstract
Measurement of field-gradient induced birefringence in certain fluids permits the direct determination of molecular quadrupole moments. Two electrode assemblies (a monopole cell and a two-wire cell) having different potential distributions were constructed to provide non-uniform electric fields of known magnitude. The cells were designed for measurements on liquids and the alternative electrode configurations gave agreement in values for the field-gradient birefringence constants of benzene and carbon disulphide.
