Electron Orbitals Measured! - Nov 15, 2009

(PhysOrg.com) -- For the first time, it has been possible to measure electron density in individual molecular states using what is known as the photoelectric effect.

Now published in Science, this method represents a key building block in the development of organic semiconductor elements. Supported by the Austrian Science Fund FWF, the success of this project rested on the mathematical transformation of the measured data. This made it possible to interpret the distribution of the electrons and draw conclusions about the potential properties of organic semiconductor elements.
