报告摘要：Take the advantage of piezoelectric controlled scanners, the amazingly spatial resolution for molecular response under tips has been achieved, which provides a perfect investigating framework for single-molecule. In this context, the optical and electric perturbations accompanied the tips are facilitating external stimuli-source for molecular probing, resulting in the high-resolution Raman and scanning tunneling microscope (STM) images, respectively. This talk will focus on the recent development of the entirely new theoretical framework for Raman images as well as the comprehensive simulations of the high-resolution STM images at the first-principles level. The practical applications for the new theory of Raman images on the different molecular responses will be discussed. In addition, the quantitative simulations of STM measurements, which provide new understandings of in-situ molecular geometrical and electronic structures, will also be given. 报告人简介：段赛，复旦大学化学系青年研究员。自主开发了可研究各类局域场光谱技术的FASTERS软件包以及能考虑所有实验参数的扫描隧道显微镜从头算模拟程序。中国化学会理论化学青年委员会首届委员，获得第九届中国化学会唐敖庆理论化学青年奖，入选国家海外层次人才计划(青年项目)、上海市海外高层次人才计划、上海市浦江人才计划和复旦大学“卓越2025”(卓学层次)人才培育计划等。
