Their bioluminescence magically     creates a starry sky just above the surface of the earth. To be more     exact, the enzyme luciferase activates the substance luciferin. The     light emitting section of luciferin is dioxetane and it converts     chemical energy into cold light by reaching its excited states     through a conical intersection.<\/p>\n<p>Loren Greenman and David Mazziotti recently studied dioxetanone by     means of quantum chemical methods. They argue that the     anti-Hermitian contracted Schrodinger equation describes both,     dynamic and static electron correlation, and that this method is     sufficiently accurate to describe the region close to the conical     intersection of dioxetanone where strong correlation has to be taken     into account.<\/p>\n<p>So, next time you spend one of these splendid summer evenings     outside, let yourself be enlightened by the fireflies to find the     ultimate solution to the electron correlation problem in quantum     chemistry.<\/p>\n<p>&#8212; Leonie Mueck<\/p>\n<p>Read more:<\/p>\n<p>L.
