<P><STRONG>Two-Dimensional Optical Spectroscopy</STRONG> discusses the principles and applications of newly emerging two-dimensional vibrational and optical spectroscopy techniques. It provides a detailed account of basic theory required for an understanding of two-dimensional vibrational and electronic spectroscopy. It also bridges the gap between the formal development of nonlinear optical spectroscopy and the application of the theory to explain experimental results.</P><br/><br/><P></P><br/><br/><P>Focusing on time-domain spectroscopy, the book presents detailed discussions on the underlying physics and interpretation methods of a variety of two-dimensional optical spectroscopic methods. It illustrates how novel diagrammatic techniques are useful in graphically describing the associated nonlinear optical transition pathways and involved population or coherence evolutions. The author also explains the basics of quantum dynamics and time-dependent perturbation theories that are requi
