Help Needed: Determining Rhodamine B Band Structure Experimentally

[hanslin]

Hi, my name is Hans Lindroth and I have difficulties understanding how to determine the band structure of a chemical substance (in this case rhodamine B) experimentally, given I have the absorption spectrum of it. Is there anybody out there who can help me with this?

If you can please help me, I'd be grateful.

Do you actually have crystals of Rh-B (or are you using it as a marker in another material) ?

Heat it up and look at its spectrum. Are you in a lab or physics department or something? You should get its emission spectra this way.

Well this is simple . Just go to a synchrotron light source and perform an XAS measurement. From that you can extract the band structure.

How about eels, electron energy loss spectroscopy. This can be performed on a sem, however as far as I know it will only give elemental decomposition
