Pentacene_2

Pentacene_2 by IBM Research - Zurich.
The delicate inner structure of a pentacene molecule imaged with an atomic force microscope. For the first time, scientists achieved a resolution that revealed the chemical structure of a molecule. The hexagonal shapes of the five carbon rings in the pentacene molecule are clearly resolved. Even the positions of the hydrogen atoms around the carbon rings can be deduced from the image. (Pixels correspond to actual data points)

In der Rasterkraftmikroskop-Aufnahme des verwendeten Pentazen-Moleküls, sind die in hexagonalen Ringen angeordneten Kohlenstoffatome und deren chemische Bindungen bestechend klar erkennbar (die hellen Strukturen im Bild) und auch die Wasserstoffatome and den äusseren Enden können eindeutig indentifiziert werden.
Die dunklen Flecke entsprechen Zwischenräumen, in denen sich keine Atome und Bindungen befinden. Die genaue Ursache weshalb die beiden Molekülendungen hell hervorstechen, untersuchen die Forscher derzeit noch. Pentazen hat eine Länge von 1,4 Nanometern (millionstel Millimeter). Die Abstände zwischen zwei Kohlenstoffatomen beträgt gerade einmal 0,14 Nanometer. Dies ist etwa 1 Million mal kleiner als der Durchmesser eines Sandkorns. Die im Bild erkennbaren "Pixel" entsprechen den einzelnen Messpunkten.

Wow, I was a bit skeptical about the atom at first, wondering if it was ever possible but nope. Here it is. Great job for us as humans.

This is the coolest thing I've seen all year. My God. That is a PICTURE of a MOLECULE.

I... just don't have the words to express my excitement and happiness, except maybe "thank you" and "congratulations."

Hi, I'm an admin for a group called Atomic Force Microscopy / AFM, and we'd love to have this added to the group!

Wonderful! This should open the door for futher exploration of other molecules too.

Oh supercool.
Please give us a few more molecules.
This is a sort of inexpressible feat.
Thank you many many times.
