Raman ir spectra
WebbIn IR spectroscopy, energy is absorbed by the bonds within a molecule, promoting electrons to excited vibrational energy levels, while Raman relies on the polarizability of a molecule. Incident radiation interacts with the electronic environment of a molecule, resulting in the perturbation of the electrons to virtual, or unquantized, energy levels. WebbI am newly joined JRF and my research project is based on high pressure raman studies. I have just started reading about raman spectroscopy, I read that pure metals cannot …
