What is the reason for splitting of soret bands in substituted porphyrins?

06 August 2020 1 7K Report

I have come across this literature about hyperporphyrins that they show a splitting of soret bands. Is it the same for porphyrin dimers and what is the reason for the origin of these kind of splitting?

Mathias O. Senge

you can work your way back through the literature from, e.g., J. Phys. Chem. A 2003, 107, 3486-3496

and see a classic Gouterman paper Can. J. Chem. 56, 1712 (1978) and work forward

1. If I can quantize the atom using this hyperbolic spiral and classical physics, could nature do the same?

If we map as a continuous motion an ionising electron (beginning its journey at n=1) in an H atom, a specific hyperbolic spiral appears (see animation). When we solve this spiral formula, we find...

Why don't d-orbitals split themselves, why does it take a ligand? why don't protons from ligand repel nucleus split d-orbitals?

why don't d-orbitals split themselves because of themselves without the presence of ligands? Electrons are indistinguishable. Why wouldn't it be more correct that protons from a ligand split the...

Why doesn't chromium 2+ ion use all its d-orbitals to receive lone pairs from six waters in [Cr(H20)6)]3+?

I'm guessing it's because the ligand experiences too much electron repulsion or proton repulsion from the chromium to insert them close to the 3d-orbitals which are close to the metal nucleus. Is...
