-Direct observation ..molecule of the solution..-.  use the polarization property of the soft X-ray of radiation light

The molecule is composed of electrons in the nucleus and the surroundings. Therefore, the character of the molecule changes greatly by the state of the electron of the intramolecular, and a lot of researches intended for the state of the electron have been done in the solid molecule and the gaseous molecule.
However, the research that observed the state of the electron like the solid molecule and the gaseous molecule, etc. was hardly done in the molecule of the liquid and the solution. To observe the electron directly, the method measured in the vacuum does it almost because it cannot do the plutonium separation of those signals by the solution sample where the evaporation of the liquid sample in the vacuum, and plural molecules exist together. The liquid and the molecule of the solution think that the research of the state of the electron is important, develop the dedicated provision that uses the soft X-ray luminescence spectroscopy that can observe the state of the electron of the intramolecular directly in advance of the world, and have developed the liquid under the atmospheric pressure and the research of the molecular electronic state in the solution sample with the Science Institute excitation order research team positively.

This time, the research group succeeded in the clear distinction of the shape of the molecular orbital to which the electron of the intramolecular was distributed by the observation using the polarization property of the character as the electromagnetic radiation of the soft X-ray. As for the molecule on a liquid inside, it has been understood that the shape of all molecular orbitals is not disarranged even if flowing always at random as a result.

It is thought that it will contribute to a fundamental science research such as the biomolecule in solution, the interaction of the ion or chemical reactions of the solution by having obtained the means to observe the molecular electronic state and the interaction in the liquid and the solution directly in the future.
Moreover, the deployment to application study of research of the interaction of the metallic ion such as chelating resins used for analysis and the rare metal recovery technique of the metal and the molecular recognition resins and molecules can be expected.

This study results precede publishing in science magazine 'Physical Chemistry Chemical Physics' of Britain, and are published in the online edition (21 June: June 22 in Japan standard time) as Advance Articles.
