Even though time-dependent spectroscopic techniques continue to push the frontier of chemical physics, they receive scant mention in introductory courses as they are poorly covered in standard texts. This text bridges the gap between what is traditionally taught in a one-semester quantum chemistry course and the modern field of chemical dynamics. It provides needed background in quantum mechanics and then discusses theory and a number of applications that are of current interest, from molecular electronics to photosynthesis. Written in a pedagogic style, it details needed computational...
