How to find the correct UV-VIS spectra of a compound looking at its wavenumber/frequency
Please see the attached photo< I  don't really understand after how to find it!

Please I have a exam in few hours, I really need to know this!

Apparently in one case energies of electronic transitions are more split than in another. There must be some structural/configurational reason behind.

Yea on spectrum A difference between electronic transitions are lower and on spectrum B difference between electronic transitions are higher! TiCl4 - is tetragonal and [Cr(H20)]3+ is linear, but still don't understand to assign them!
