In situ UV–visible spectroscopy integrated to the Langmuir trough. (a) Schematic diagram, showing the double absorption of the light by the layer after reflection on a Si wafer. (b) Annotated picture of the setup. (c) Absorbance spectra of a PCDA Langmuir film under continuous UV irradiation as measured with the setup shown in (a) and (b). |
