Abstract
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 degreesC. Accoun ting for the changes in the SHG polarization behaviour with temperature to extract the relative temperature dependence of chi (zzz) shows that it is s imilar to that obtained from simulation studies. The role of the interfacia l refractive index in the interpretation of the SHG signals is addressed.
