This project focuses on achieving control of molecular motion and quantum state character through coherence effects inherent in the laser molecule interaction. In addition, applications of these effects in photodissociation dynamics will be investigated by using both the enhanced level of state selectivity as well as the possibility of creating coherent superpositions of quantum states for the purpose of developing possible bond breaking control mechanisms. Specific experiments include alignment using the Autler-Townes splitting, modification of the singlet vs triplet character of a dressed molecular wavefunction, measurement of the transition dipole moments using electomagnetically induced transparency and finally control of photodissociation and bond breaking dynamics. In a broader sense, the project will provide research opportunities for minority students as well as create opportunities in industry for the undergraduate students.

本项目的重点是通过激光分子相互作用中固有的相干效应来实现分子运动和量子态特征的控制。此外，这些效应在光解动力学中的应用将通过使用状态选择性的增强水平以及为开发可能的键断裂控制机制而创建量子态相干叠加的可能性来研究。具体的实验包括利用奥特勒-汤斯分裂进行对准，修饰分子波函数的单线态和三重态特征，利用电磁诱导透明测量跃迁偶极矩，最后控制光解离和键断动力学。从更广泛的意义上讲，该项目将为少数民族学生提供研究机会，并为本科生创造行业机会。
