Summary:An investigation of the polarization and temperature dependence of surface second-harmonic generation (SHG) at the air-water interface shows that the intensity of the SHG signal decreases over the range 20-70°C. Accounting for the changes in the SHG polarization behaviour with temperature to extract the relative temperature dependence of X zzz shows that it is similar to that obtained from simulation studies. The role of the interfacial refractive index in the interpretation of the SHG signals is addressed.
