measurements of the infinite-dilution molar field-gradient birefringence constants, kerr constants and cotton-mouton constants of furan, thiophen and selenophen as solutes in cyclohexane at 298k and 632.8 nm are reported. analysis of the observations, in conjunction with other known electric and magnetic properties of these molecules, yields for each the out-of-plane component of the quadrupole moment relative to the effective-quadrupole-centre combination of these results with centre-of-mass quadrupole moments from microwave zeeman spectroscopic studies leads to low-precision estimates of the position of the effective-quadrupole-centre and of the relevant combination of elements of the a and g minutes tensors
