4reaction mechanism — Introduction in chemical reactions (chemical reaction), the detailed processes by which chemical substances are transformed into other substances. The reactions themselves may involve the interactions of atoms (atom), molecules (molecule),… …
5Internal conversion (chemistry) — Internal conversion is a transition in from a higher to a lower electronic state in a molecule. It is sometimes called radiationless de excitation , because no photons are emitted. It differs from intersystem crossing in that, while both are… …
6Molecular models of DNA — While this purified DNA precipitated in a water jug (left) appears to be a formless mass, nucleic acids actually possess intricate structure at the nanoscale (right). M …
