Ok, so doing a lab report, I'm having a bit of a retard moment... Think I might have forgotten about d-electron counts. I'm looking at my UV-VIS spectra for [VO4]3-, [CrO4]2- and [MnO4]-, and as far as I can see they are all d-zero complexes, so where does the colour come from?

Or the transitions given altogether for that matter

I'm bumping this shit, it's already late and I can't find shit on this even in shriver & atkins, which makes this fucking gay.

nothing is d0 dummy. they all are d-something, then the oxygens count negatively towards that total.

Yeah sure, don't you love it when you have a negative amount on d-electrons....

Of course there are d0 complexes you faggot
