Description/Abstract
The air/water interface of aqueous (t-butyloxycarbonyl)- tryptophan-tryptophan (Boc-Trp-Trp) has been studied by surface second harmonic generation (SHG). The SHG signals obtained with a linearly polarised fundamental indicate a Langmuir-like adsorption isotherm. Wavelength-dependent circularly differential harmonic generation (SHG-CD) was observed together with SHG optical rotation. The SHG signals from the LL and DD enantiomer show equal but opposite dependence on the handedness of the fundamental radiation and the DL diastereoisomer gave rise to a different spectrum.
