Two-dimensional infrared spectra of isotopically diluted amyloid fibrils from A beta 40

The 2D IR spectra of the amide-I vibrations of amyloid fibrils from A beta 40 were obtained. The matured fibrils formed from strands having isotopic substitution by super(13)CFormula super(18)O at Gly-38, Gly-33, Gly-29, or Ala-21 show vibrational exciton spectra having reduced dimensionality. Indee...
