Introduction to Ultrafast Spectroscopy

Two dimensional infrared spectroscopic technique is a novel method to study structure and dynamics of biological molecules. Understanding the complicated submicroscopic structure and their dynamics are beyond our real life imagination. It is obvious that the 2DIR technique is as complicated as the understanding of molecular structure and dynamics. But the basic ideas are hidden under the simple real life experiences. Here we make an analogy with those simple phenomena to explain the complicated 2D1R method.
