Abstract
The air/water interface of aqueous tryptophan and (t-butyloxycarbonyl)-tryptophan-tryptophan (Boc-Trp-Trp) has been investigated using the technique of interfacial second harmonic generation (SHG). The SHG response for both linearly and circularly polarized incident radiation has been recorded. For tryptophan no special response was observed for circularly polarized light but for Boc-Trp-Trp a wavelength dependent circularly differential harmonic generation (SHG-CD) and SHG optical rotation was observed.
