Laser Light in Chemistry

Laser techniques have developed rapidly. Picosecond pulses became possible at the beginning of the 1990s. The time resolution of very fast photochemical reactions was improved considerably. Here, we are talking about time constants of the same order of magnitude as vibration cycles. Fast biochemical reactions, for example, the
