Using high-resolution atomic force microscopy, a hydrogen bond has been imaged for the first time. This technique is quite similar to the one used to photograph bonds breaking and reforming that was announced earlier this year.
What I find fascinating is that the geometry of the molecule itself contains minute variations, showing the way that it adapts according to the forces within it. Where the diagramatic model shows perfect symmetries, nature has that minute adaptation and vibrancy. Beautiful. What an achievement.
