I'm a student from India and I was reading up on the crystal field theory, from Concise Inorganic Chemistry (by J.D.Lee). (low price edition) I am new so sorry if i posted in the wrong place.
My doubt is this:
On page 206-207, the author takes about calculation of :delta:o for [Ti(H2O)6]3+ from the Uv spectra curve. It says:
The curve plots Molar absorbance against decreasing wavenumber in cm-1.
The part of the curve from 27000 to 30000 cm-1 is steep due to charge transfer. (my doubt: What does this mean?). The broad peak of the curve at 27300 cm-1 represents the d-d transition from the t2g orbital to the eg orbital. (My doubt: why should there be this peak?)
I have enclosed a rough diagram i drew using MS Paint.
Please explain as clearly as possible.
