Coherent two-dimensional infrared spectroscopy (2D IR) uses a series of IR femtosecond laser pulses to pump and then probe the response of a system, making it possible to learn much more about the structure and dynamics of molecules than can be seen with one-dimensional IR spectroscopy. The technique’s inventor, Martin T. Zanni of the University of Wisconsin-Madison, discussed 2D IR in a 2013 interview in Spectroscopy (1). Since 2013, Zanni has applied 2D IR spectroscopy to new systems and has started a company, PhaseTech Spectroscopy, Inc., to commercialize the technique.

Our survey of the spectroscopy of the C–O bond continues. Here, we complete our discussion of alcohols and discuss how to distinguish pure alcohols, alcohol–water mixtures, and pure water from each other.

The number and position of C-O stretches will help us identify functional groups such as alcohols and ethers, and will help us distinguish between members of the same molecular class.
