Infrared Spectroscopy as a Probe of Electronic Energy Transfer

Thomas Rizzo, Aleksandra Zabuga, Antonio Prlj, Valeriu Scutelnic

We have combined electronic and vibrational spec- troscopy in a cryogenic ion trap to produce highly resolved, conformer-selective spectra for the ground and excited states of a peptide containing two chromophores. These spectra permit us to determine the ...

IR-induced conformational isomerization of a helical peptide in a cold ion trap

Thomas Rizzo, Caroline Seaiby, Annette Svendsen, Aleksandra Zabuga

In this work we use laser-induced population transfer techniques to study the conformational isomerization of a helical peptide, Ac-Phe-(Ala)5-LysH+, in a cold ion trap. In one scheme, called IR-UV hole-filling spectroscopy, a single conformation is select ...

Franck–Condon-like Progressions in Infrared Spectra of Biological Molecules

Thomas Rizzo, Aleksandra Zabuga, Michael Zachary Kamrath

Infrared spectra in the NH stretch region are often used for structure determination of gas-phase biological molecules. Vibrational couplings complicate the structure determination process by giving rise to additional vibrational bands along with the expec ...
