Research overview

Dr Couling’s research group is concerned with the precise and accurate experimental measurement of the fundamental optical, electric and magnetic properties of molecules, as well as with the measurement and modelling of molecular interaction effects.

Current projects

Current projects include the measurement of depolarized Rayleigh light-scattering, and measurements of the Kerr and Buckingham effects (where polarized laser light passes through a medium in the presence of a strong electric field or electric field gradient, respectively, thereby inducing a measurable birefringence). This allows for the determination of fundamental molecular electric properties, including the (hyper)polarizabilities and quadrupole moments.
