Abstract

Molecular photography can be used in the undergraduate chemistry laboratory for identification of functional groups using scanning tunneling microscopy. Easy-to-use scanning probe microscopes (SPMs) can have an important role acting as atomic or molecular cameras. Students not only take snapshots of atoms of bare surfaces but also identify chemically significant portions of molecular adsorbates placed on the surfaces. Students feel empowered as they obtain visual evidence for concepts that have seemed abstract.
