Gas phase spectroscopy of the pentapeptide FDASV

Abo-Riziq A, Bushnell JE, Crews B, Callahan M, Grace L, De Vries MS

IR-UV double resonance spectroscopy of the laser-desorbed, jet-cooled pentapeptide FDASV shows only one type of conformer in the gas phase. Comparison with computations at the B3LYP/6-31G** level suggests formation of an alpha-turn in the absence of solvent stabilization. (c) 2006 Elsevier B.V. All rights reserved.
