We use infrared spectroscopy to demonstrate the critical role that trace O2 plays in determining the products formed when a [2Fe2S] cluster protein reacts with nitric oxide (NO). The observed ...

We have studied the structure of (Ala)5, a model unfolded peptide, using a combination of 2D IR spectroscopy and molecular dynamics (MD) simulation. Two different isotopomers, each bis-labeled with ...
