There are four images each, which one is the model and which one's the scanning/microscopy?
Images A for pentacene and image C for cephalandole A are definitely models.The rest, I'm not sure. They're either STM or AFM. But notice image D of pentacene, those are individual molecules that we can see under those techniques!
Wao--! It's really cool! there are another cool thing is that the scientist can picture out those structures before they see it.
