Are Orbitals Real?!
Vitalii | 26 Jul, 2007, 14:56 | General | (7856 Reads)

Paper "Tomographic imaging of molecular orbitals" by J. Itatani. in Nature challenges common QM (quantum mechanics) interpretation of orbitals as pure mathematical constructs.
Authors goes as far as to say that they experimentally measured HOMO (highest occupied molecular orbital). Is that possible indeed or is it just a wrong interpretation of the experiment?

The paper could be found at:

I appreciate your comments on this issue.

[1] Orbitals

Orbitals are used as a basis to construct wavefunction.
Can one measure a basis?
Of course not!
It is similar to the claim that one has made a tomography of the X axis.

of course the real thing is the configuration. but it seems to me that the one electron orbitals are a pretty good approximation because you are able to measure their energies with XPS and because Hartree-Fock works. therefore it makes sense to me that you can also find their shape experimentally.

I have to say that I don't really know anything about wave packet dynamics though
