Pulsed technology

In this type of reaction, reactant molecule A can be activated coherently by photochemical irradiation using a femtosecond laser pulse, and activated A undergoes a subsequent reaction without collision with other molecules. It is very difficult, in principle, to adjust collisions of two molecules coherently. Therefore, it is rather difficult to apply femtosecond laser pulse technology to conduct a bimolecular reaction, shown in Equation (2.2), like a unimolecular reaction. It is difficult to achieve the collision of two molecules A and B coherently.

Experimentally, the simplest and most effective method of control is to shape the temporal and frequency profile of the femtosecond laser pulse. Technology that allows us to produce tailored femtosecond laser pulses is now available, and... 

It should be noted that value Vg strongly depends on the experimental techniques used in measurement. The time-consuming, error-causing ways should be avoided (such as the surface titration method), and instead a much simpler way i.e. pulse technology could be used. When the measurement of chemisorption is carried out by the pulse technology at room temperature, the nature of the support does not relate to the fraction of the metal. Because it provides a more precise measurement for turnover frequency, this approach has opened up a new prospect for fundamental research. 

We could not always discriminate clearly between evaluation and measurement technologies. The Hall effect and lifetime measurements in semiconductors are frequently part of evaluation technology. The measurement technologies require various sophisticated extreme technologies including pulse technology to clarify extreme characteristics. Such inconsistent requirements as simultaneous measurements of static and dynamic properties are one of the problems to be solved.
