Single-molecule spectroscopy
Article Abstract:
Single-molecule spectroscopy (SMS) in solids is a rather new field, seven years old in 1998. Fewer than 20 solvent-solute systems exist for which spectral lines have been observed. In this method only one probed molecule is studied and the light from the molecule should be separated out from experimental noise. Photon correlations are helpful for single quantum systems (SQSs, or atoms, ions, or molecules). The experiment is synchronized with photons emitted by the SQSs. There is not yet an application for the SMS technique, but possibilities exist, among them low-temperature dynamics in solids and quantum optics/computations.

Ab initio dynamics of surface chemistry
Article Abstract:
Ab initio molecular dynamics (AIMD) techniques can be applied to molecule-surface reactions. Methods include an analytic potential energy function to fit to data. Different aspects of a problem can be illustrated with H2 desorption and adsorption from the Si(100)-2 x 1 surface. It is not yet possible to perform calculations that constitute fully ab initio molecular dynamics simulations of large, realistic systems over long time periods, but that is a distant goal for this theoretical method.

Reflections on physical chemistry: Science and scientists
Article Abstract:
The story of a young scientist from Tel Aviv who went on to become the first chairman of the Chemistry Department of the newly formed Tel-Aviv University is illustrated. He has explored the phenomena of energy acquisition, storage and disposal and structure-dynamics-function relations in large molecules condense phase, clusters and biomolecules.
