Abstract

Prokhorenko et al. (Research Articles, 1 September 2006, p. 1257) reported that, in the weak-field regime, the efficiency of retinal isomerization in bacteriorhodopsin can be controlled by modulating the spectral phase of the photoexcitation pulse. However, in the linear excitation regime, the signal measured in an experiment involving a time-invariant, stationary process can be shown to be independent of the pulse spectral phase.

摘要

普罗霍连科等人（《研究论文》，2006年9月1日，第1257页）报告称，在弱场条件下，细菌视紫红质中视网膜异构化的效率可通过调节光激发脉冲的光谱相位来控制。然而，在线性激发条件下，在涉及时间不变的平稳过程的实验中测得的信号可证明与脉冲光谱相位无关。
