Physicists Resolve Long-Standing Mystery of Structure-Less Transition

Electron density distribution of the frontier orbital of a TMTTF molecule. Electrons of the constituent atoms of the molecule can be considered as either core electrons, which have no interactions with the surroundings, or electrons of frontier orbitals, which determine many physical properties of the molecule. We succeeded in visualizing the frontier molecular orbital distribution of a TMTTF by precise structural analysis using a core differential Fourier synthesis (CDFS) method. Credit: Shunsuke Kitou

Researchers probe a mysterious phase transition in an organic molecular conductor using synchrotron X-ray radiation. We normally associate conduction of electricity with metals. However, some of the high measured conductivities are found in certain organic molecular crystals...
