PNNL: Toppling Raman Shift in Supercritical Carbon Dioxide

Source:  PNNL News Release, February 29, 2012.

Just as a wine glass vibrates and sometimes breaks when a diva sings the right note, carbon dioxide vibrates when light or heat serenades it.  When it does, carbon dioxide exhibits a vibrational puzzle known as Fermi resonance.  Now, researchers studying geologic carbon storage have learned a bit more about the nature of carbon dioxide.

The results provide clues to the nature of the Fermi resonance in other molecules and will help researchers better understand details in chemical reactions. The team of researchers from the Department of Energy’s Pacific Northwest National Laboratory reported their findings in the February 28 issue of the journal in Physical Chemistry Chemical Physics.
