Trying to find absorption/emission data or charts

I've been looking for the excitation/emission wavelengths of various plant pigments.

I've found some charts, but they tend not to show the UV or the IR regions.

Things have been busy, so I haven't had a lot of time to devote to this.

If you find charts or data, please post pics or links here.

Thanks!

This seems to show us that there's no IR fluor in chlorophyll ?? But we don't get to see past 750 nm.

Olive oil fluoresces !! Who knew ??!! Cool.

 

Added: I suppose this should have been obvious given that olives for oil are green?
