Question:
As a project at school we were to separate the four main photosynthetic pigments chlorophyll a and b, carotene and xantophyll and then investigate the absorption of light of these four pigments in the visible region of light. We were then to compare our absorption spectra with the "correct" ones. I had no problem in finding spectra for chlorophyll a, b and carotene. However, I could not find one for xantophyll. Do you have one or do you know somewhere that I can look for it?


Replies:
Try doing a google image search using the key words, "xanthophyll absorption spectra", and you should find what you are looking for.
