Abstract

The parallel and synergistic developments of atomic resolution structural information, new spectroscopic methods, their underpinning formalism, and the application of sophisticated theoretical methods have led to a step function change in our understanding of photosynthetic light harvesting, the process by which photosynthetic organisms collect solar energy and supply it to their reaction centers to initiate the chemistry of photosynthesis. The new spectroscopic methods, in particular multidimensional spectroscopies, have enabled a transition from recording rates of processes to focusing on mechanism. We discuss two ultrafast spectroscopies - two-dimensional electronic spectroscopy and two-dimensional electronic-vibrational spectroscopy - and illustrate their development through the lens of photosynthetic light harvesting. Both spectroscopies provide enhanced spectral resolution and, in different ways, reveal pathways of energy flow and coherent oscillations which relate to the quantum mechanical mixing of, for example, electronic excitations (excitons) and nuclear motions. The new types of information present in these spectra provoked the application of sophisticated quantum dynamical theories to describe the temporal evolution of the spectra and provide new questions for experimental investigation. While multidimensional spectroscopies have applications in many other areas of science, we feel that the investigation of photosynthetic light harvesting has had the largest influence on the development of spectroscopic and theoretical methods for the study of quantum dynamics in biology, hence the focus of this review. We conclude with key questions for the next decade of this review.

以光合作用采光为例,说明多维生物分子光谱学的发展和应用。
原子分辨率结构信息、新光谱方法、其基础形式主义以及复杂理论方法应用的平行和协同发展,使我们对光合作用光收集的理解发生了阶跃性功能变化,光合作用光收集是光合生物收集太阳能并将其提供给反应中心以启动光合作用化学反应的过程。新的光谱学方法,尤其是多维光谱学,实现了从记录过程速率到关注机制的转变。我们讨论了两种超快光谱法--二维电子光谱法和二维电子振动光谱法--并通过光合作用采光的视角说明了它们的发展。这两种光谱法都能提高光谱分辨率,并以不同方式揭示能量流动和相干振荡的途径,这些途径与电子激子(激子)和核运动等量子力学混合有关。这些光谱中的新型信息促使人们应用复杂的量子动力学理论来描述光谱的时间演变,并为实验研究提供了新的问题。虽然多维光谱在许多其他科学领域都有应用,但我们认为光合作用光收集的研究对生物量子动力学研究的光谱和理论方法的发展影响最大,因此是本综述的重点。最后,我们提出了本综述下一个十年的关键问题。

期刊介绍: Quarterly Reviews of Biophysics covers the field of experimental and computational biophysics. Experimental biophysics span across different physics-based measurements such as optical microscopy, super-resolution imaging, electron microscopy, X-ray and neutron diffraction, spectroscopy, calorimetry, thermodynamics and their integrated uses. Computational biophysics includes theory, simulations, bioinformatics and system analysis. These biophysical methodologies are used to discover the structure, function and physiology of biological systems in varying complexities from cells, organelles, membranes, protein-nucleic acid complexes, molecular machines to molecules. The majority of reviews published are invited from authors who have made significant contributions to the field, who give critical, readable and sometimes controversial accounts of recent progress and problems in their specialty. The journal has long-standing, worldwide reputation, demonstrated by its high ranking in the ISI Science Citation Index, as a forum for general and specialized communication between biophysicists working in different areas. Thematic issues are occasionally published.
