A collection of papers from a conference held in Toledo, Spain, in September 2001. The contributions are from international scientists and they examine the state-of-the-art of femtochemistry and femtobiology at the beginning of the new millennium. There are reviews and papers on ultrafast dynamics in molecular science. The coverage of topics highlights several important features of molecular science from the viewpoint of structure (space domain) and dynamics (time domain). First of all, the text presents developments, such as experimental techniques for understanding ultrafast processes in...
