I'm looking for a graph showing absorption spectrum of indole-3-acetic acid in the wavelengths of visible light, but I was only able to find its spectrum in the UV. Is there a form of online database showing this kind of information?
Hi I'm not sure whether indole-3-acetic acid gives absorption peak at visible range or not (I don't have the chemical) but you can try find it in NIST database. However judge from the structure itself I doubt it gives an absorption peak at visible range.
Link as below, hope it helps.

Thank you for your answer, it was very clear.
Unfortunately on NIST I have only found IR absorption spectrum of indole-3 acetic acid, and not the UV/Vis one.
I was looking for visibile light AS because it has been used as photosensitizer in photodinamic therapy after exposition with green light, but absorption spectrum on visible light has never been reported
Thank you Dr. Van der Zwan for the exhaustive and accurate answer to my question. Looking at the absorption spectra reported in paper1, how is it then explainable the demonstrated [Na et al] peak of production of free radicals after irradiation of Indole 3 acetic acid with visible light (specifically at 470 and 520 nm wavelenghts)?
I do work in a clinical dermatology setting, so in order to assess such kind of experiment I would have to ask to a photochemistry lab. If the experiment of Na and coworker led to the wrong detection of ROS produced by DCFH-DA and not by IAA, how are explainable the clinico-pathological effects that IAA irradiated with green light seemed to exert in their works?
