摘要：

Recently, new methods for determining time-evolving structures using infrared analogs of NMR spectroscopy have been introduced that have outstanding potential in structural biology. Already, within the past two years, structures of dipeptides, tripeptides and pentapeptides have been determined on much faster timescales than the conformational dynamics. Also, two-dimensional infrared correlation spectra of some proteins and isotopically edited alanine-rich helices have been examined.
