Collision complexes clocked in real time
Article Abstract:
The lifetime distribution of collision intermediates in chemical reactions has been determined for the first time. A.H. Zewail and colleagues at the California Institute of Technology used femtosecond laser spectroscopy to obtain real time measurements of reaction collision complexes' lifetimes, a necessary step toward understanding chemical reaction dynamics. The obtaining of higher collision energies through photodissociating the CH3Br.I2 van der Waals molecule and observing the BrII complex should be the next steps.

Measuring the immeasurable
Article Abstract:
The use of lasers to study the intermediate stages of chemical reactions has led to the development of techniques such as femtosecond spectroscopy. Femtochemistry applications have revealed previously unknown classes of reaction for example in photosynthesis.
