Signatures of incoherent mixing pathways in action-detected spectroscopies

Incoherent population mixing creates a large background in ultrafast, action-detected pump-probe and 2D spectroscopies. This background often obscures the desired coherent responses and leads to incorrect assignment of spectral features. In a previous study, we postulated three c...

Decongested 2D IR Spectra Reveal N-Terminal Helices in Amyloid Oligomers Associated with Type 2 Diabetes

Abstract Oligomeric peptides are implicated in amyloidosis, yet only a few atomic structures of amyloid oligomers have been identified. Recently, we reported an atomic structural model of human islet amylin polypeptide (hIAPP) oligomer [Shivani, S. T.; et al.Proc. Natl. Acad. Sci...
