The physical understanding of chemical reactivity builds on the connection between structural and dynamical molecular properties, such as the specific dynamical properties of functional groups which determine a molecule's chemical behavior. Studies of OH- and NH2 groups in different environments demonstrate how experiment and theory combine to draw a detailed picture of the molecular quantum-dynamics. The hydrogen motion in a series of model systems elucidates important aspects of the N/O/H chemistry, with implications for radical and atmospheric chemistry. In perfect analogy to the separation of electronic and nuclear motion in the Born-Oppenheimer approximation, characteristic motions of individual structural features are adiabatically separated from the overall system dynamics. This phenomenon of vibrational adiabaticity will play a central role in the understanding of the microscopic foundations of empirical structure–reactivity relationships.Downloads
