Multidimensional Spectroscopic Studies of Condensed Phase Dynamics

在这个由化学学部化学结构、动力学和机制项目资助的项目中，加州大学伯克利分校的Graham Fleming教授将开发和扩展光谱方法，用于研究量子受限系统，如碳纳米管、量子点和分子系统。该方法是使用二维超快电子光谱学来简化光谱，并揭示动力学的基本量子力学方面。非常高的时间分辨率，各种偏振序列和混合时频方法将被应用于揭示复杂量子系统的基本方面。更广泛的影响包括在世界范围内传播新技术，使广泛的受众参与能源安全和气候变化问题，教育和激励来自当地服务不足的高风险地区的年轻女性，并为学校科学课程的学生提供远程学习机会。这项工作将扩大对光电应用的量子限制系统的理解，范围从显示技术到太阳能到电能和/或化学能的转换。

In this project funded by the Chemical Structure, Dynamics and Mechanisms program of the Chemistry Division, Professor Graham Fleming of the University of California, Berkeley will develop and extend spectroscopic methods for the study of quantum confined systems such as carbon nanotubes, quantum dots, and molecular systems. The approach is to use two-dimensional ultrafast electronic spectroscopy to simplify spectra, and to reveal fundamental quantum mechanical aspects of the dynamics. Very high time resolution, various polarization sequences, and mixed time-frequency methods will be applied to reveal fundamental aspects of complex quantum systems. The broader impacts involve disseminating the new techniques world-wide, engaging a very wide range of audiences in the issues of energy security and climate change, educating and inspiring young women from high-risk underserved areas of the local area, and developing distance learning opportunities for students in school science programs.This work will expand the understanding of quantum confined systems for opto-electronic applications ranging from display technology to the conversion of solar energy to electricity and/or chemical energy.
