The2D IR technique obtains both staticand dynamic mo lecular information through exciting molecular vibrations with ultrafast MidIR lasers. It is an IR analogue of two dimensional NMR, but six orders of magnitude faster. It has been widely applied to studies of molecular interac tions, hydrogen bond dynamics, fast chemical exchanges, staticand transient structures of peptides and proteins. More applications would be expected in the near future.
