Optical spectroscopy is going through a revolution akin to that which occurred in Nuclear Magnetic Resonance in the 1970’s. The ability to produce tunable femtosecond and picosecond optical pulses in the infra-red allows the measurement of vibrational coupling in a reliable and rigorous fashion. This class of spectroscopy has become known as two dimensional infra-red spectroscopy or 2DIR. Multipulse measurements combined with quantum mechanical calculations allow reliable interpretation of such data which in turn allows these methods to be usefully applied to the study of a wide range of soft condensed matter. In particular these methods show great promise for the study of proteins and a number of applications are suggested and illustrated ranging from proteomic screening through ultrafast dynamics to structural analysis.
