The first published source of material on the principles of the subject, this book 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. The author presents novel definitions and theoretical frameworks for linear and nonlinear response spectroscopy and describes a range of two-dimensional spectroscopic techniques to compare the merits and disadvantages of...
