Response to Comment on “Engineering coherence among excited states in synthetic heterodimer systems”

Dugan Hayes; Graham B. Griffin; Gregory S. Engel

<jats:p>Halpin, Johnson, and Miller contest our assignment of quantum beating signals observed in the two-dimensional electronic spectra of a series of fluorescein heterodimers to electronic coherences. Here, we present resonance Raman spectra, statistical analysis on multiple data sets, and an explanation of differences between the family of molecules described in our Report and the homodimer examined by the commenters. We contend that these results all support our assignment of the beating signals to electronic coherences.</jats:p>

Comment on “Engineering coherence among excited states in synthetic heterodimer systems”

Alexei Halpin; Philip J. M. Johnson; R. J. Dwayne Miller

<jats:p> Hayes <jats:italic>et al</jats:italic> . (Reports, 21 June 2013, p. 1431) used two-dimensional (2D) electronic spectroscopy to study molecular heterodimers and reported a general mechanism for the prolongation of electronic coherences, consistent with previous interpretations of 2D spectra for light-harvesting systems. We argue that the dynamics attributed to electronic coherences are inconclusive based on experimental inconsistencies arising from limited sample characterization and insufficient control measurements. </jats:p>
