Nonlinear Responses of Coupled Vibrators through Frequency Resolved and Heterodyned Femtosecond Infrared Echoes

Not Accessible

Your library or personal account may give you access

Abstract

The coherent signals that yield two-dimensional infrared spectra of peptides at 6μ are obtained. Spectrally resolved heterodyned echoes or transforms of frequency integrated echoes show resolved spectra and level specific dynamics of dipeptides and tripeptides.
