Abstract

The nonlinear optical properties of the macromolecule nitrocalix[4]arene have been studied by means of surface second-harmonic generation (SSHG). Those properties are controlled by the polarizability and hyperpolarizability tensors α(ω), β(2ω), (ω: angular frequency), commonly studied in a solvent using Rayleigh and hyper Rayleigh scattering (HRS). Measurements of that type yield only limited information about the induction, given by: due to orientational averaging (p: dipole strength, EL: local field).
