Advanced Physical Chemistry topics consist of different spectroscopic methods ranging from ultrafast and mass spectroscopy, nuclear magnetic and electron paramagnetic resonance, x-ray absorption and atomic force microscopy , also theoretical and computational tools. The gap between the theories and techniques of modern-day physics and chemical systems is filled by Physical chemistry . Physical and theoretical chemists work to unravel the phenomena that govern all aspects of the physical world by using advanced characterization and computational methods . Advanced characterization techniques is applied to a diverse range of topics – energy storage materials for electric vehicles, biologically relevant proteins to understand degenerative diseases, photo-induced molecular transformations and complex surface properties by Physical chemists . As to improve our understanding of all aspects of chemistry , right down to the nature of chemical bonding , Theoretical chemists work to establish quantum mechanical methods.
