Polarisation Dependence

The SHG signal was recorded at fourteen input polarisations for each of three output polarisations at several aqueous concentrations of the crown ether. This allows the determination of the orientation of the crown ether at the interface. A typical set of results at a concentration of 4 mM is presented in figure 7:
