Abstract
The two dimensional (2D) photon echo spectrum of the amide ultraviolet (UV) bands of proteins are simulated. Two effective exciton Hamiltonian parameter sets developed by Woody and Hirst, which predict similar CD spectra, may be distinguished by their very different 2DUV spectra. These differences are enhanced in specific configurations of pulse polarizations which provide chirality-induced signals.
摘要
模拟了蛋白质酰胺紫外（UV）波段的二维（2D）光子回波光谱。伍迪和赫斯特开发的两组有效的激子哈密顿参数集，虽然预测出相似的圆二色（CD）光谱，但可以通过它们非常不同的二维紫外光谱来区分。在提供手性诱导信号的特定脉冲偏振配置中，这些差异会增强。
