The Chemistry Division through its Chemical Instrumentation Program, its Experimental Physical Chemistry Program, and its Inorganic/Bioinorganic/Organometallic Chemistry Program supports a research project involving a large number of MIT scientists working within the George R. Harrison Spectroscopy Laboratory on the development and application of modern laser spectroscopic techniques to a wide range of fundamental problems. Led by Professors Feld and Steinfeld and Dr. Dasari, this endeavor has achieved efficient collaborative use of expensive optical facilities, while becoming a model for effective training of large numbers of students in state-of-the-art optical techniques. Multiple-resonance and nonlinear laser techniques are being used to study the spectroscopy of highly excited electronic and vibrational levels (including the regime of quantum chaos) and to follow the evolution of phase, velocity, and quantum states in collisional processes. Raman and resonance Raman techniques are being used to study diverse systems, ranging from technetium pharmaceuticals to enzymes. Pump-probe studies of the conversion of light to chemical energy are being investigated with nanosecond to femtosecond techniques. New work is being initiated to investigate photochemical processes at surfaces, interfaces, or in bulk materials and to develop spectroscopic instrumentation for deployment at hydrothermal vents on the ocean floor.

化学系通过其化学仪器项目，实验物理化学项目，它的无机/生物无机/有机金属化学项目支持一个研究项目，涉及大量麻省理工学院的科学家在乔治·r·哈里森光谱学实验室工作，研究现代激光光谱学技术的发展和应用，以解决广泛的基本问题。在菲尔德教授、斯坦菲尔德教授和达萨里博士的领导下，这项努力实现了昂贵光学设备的高效协同使用，同时成为大量学生在最先进光学技术方面有效培训的典范。多共振和非线性激光技术被用于研究高激发电子和振动能级（包括量子混沌状态）的光谱，并跟踪碰撞过程中相、速度和量子态的演变。拉曼和共振拉曼技术被用于研究从锝药物到酶的各种系统。用纳秒到飞秒技术研究光到化学能转换的泵-探针研究。研究表面、界面或散装材料的光化学过程的新工作正在启动，并开发用于海底热液喷口部署的光谱仪器。
