Effect of cycloalkanone ring size on second and third order nonlinear optical properties of bischalcones

Investigation of enhanced third-order optical nonlinearity in novel coenzyme A capped silver nanoparticles

“…By measuring this displacement, the refractive index of the sample can be measured, which is given by: 38 where n a is the refractive index of air, the Δ is the lateral displacement, d is the separation between the walls of the cuvette, and θ is the angle of incidence.…”
