Discerning vibronic molecular dynamics using time-resolved photoelectron spectroscopy
Article Abstract:
Recent research has produced time-resolved photoelectron spectroscopy measurements that distinguish vibrational dynamics from the coupled electronic population dynamics, linked with the photo-induced internal conversion, in a linear unsaturated hydrocarbon chain. This method was demonstrated by studying ultrafast internal conversion in a linear polyene, all-trans 2,4,6,8 decatetraene. It is suggested that this method could offer new views about the scope and timescale for the onset of statistical behaviour in an isolated, energized molecule.

Dynamics of glasses below the glass transition
Article Abstract:
Scientists have observed changes in the interfacial mobility of glass-forming molecules within confined films when the film thickness is modified. An increase in film thickness reduces the speed of molecular motion in glass-forming liquids. Relaxation behaviour of molecular motion is illustrated by second-harmonic generation research.

Volunteering leads to rock-paper-scissors dynamics in a public goods game
Article Abstract:
In public goods experiments, initial cooperation can be maintained by the opportunity to punish defectors or the need to maintain good reputation. With optional participation in the public goods game, loners, defectors and cooperators will coexist through rock-paper-scissors dynamics.
