Hello,

In most of the papers like

http://eprints.qut.edu.au/4763/1/4763.pdf

one sees the raman spectra of crystals or molecules and the peaks are not further described (if they are stokes or antistokes). Do all the Peaks belong to the Anti-stokes-lines? And if it is so, why don't we see any stokes-lines?

Thanks

Raman processes are rather rare events (compared to the Rayleigh peak), with, in general, Stokes scattering occurring more often than Anti-Stokes events. This leads to instrumentation that uses the Stokes "regime" to collect data.

Not really a source, but nevertheless some resource: http://www.raman.de/htmlEN/basics/intensityEng.html

From the BCS theory of superconductivity is well known that the superfluid density smoothly decreases with increasing temperature. Annihilated superfluid carriers become normal and lose their momenta on lattice atoms. So if we induce a persistent supercurrent in a ring below Tc and after that slowly increase the temperature, we must observe a decrease in the actual supercurrent, because the density of electron pairs and total supercurrent momentum decrease. However, this supercurrent...
Hi. I have got question as in title. How can idea of instantaneous dipole moment for atoms like, for example hydrogen be consistent with idea of orbitals? At my level of knowledge London dispersion forces are derived taking into account Bohr model of atom. But we know today that this model is not correct. If it would be correct I understand that at each time electron is at some point at radius at some angle and there is dipole moment at this time from nucleus to electron at orbit. But how...
