Hayes et al. (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.
海耶斯等人（报告，2013 年 6 月 21 日，第 1431 页）使用二维（2D）电子光谱研究分子杂二聚体，并报告了一个延长电子相干的一般机制，与先前对光捕获系统的 2D 光谱的解释一致。我们认为，基于实验不一致性，归因于电子相干的动力学是不确定的，这些不一致性源于有限的样品特征描述和不足的控制测量。
