CRIF:MU - Tunable UV-Vis and IR Laser System for Spectroscopy and Chemical Dynamics Research

在化学研究仪器和设施：多用户计划（CRIF：MU）的支持下，杨百翰大学化学系将为一个新的共享激光设施购买两个光学参量振荡器（OPO）激光系统。激光系统将被化学系研究人员（教师，研究生和本科生研究人员）用于研究化学科学中的一些问题。 其中包括：（1）有机金属物质和视黄醛的光化学动力学;（2）超分子离子的气相结构和键合;（3）通过光腔衰荡光谱的气相自由基动力学;和（4）气相物质中的振转能量转移。激光系统将被大量的本科生和研究生用于研究和实验室课程。将通过一项针对代表性不足群体的高中生的大学方案，扩大对该文书的利用。 作为拓展计划的一部分，高中生将参观实验室，一些学生将与杨百翰大学的本科生和研究生研究人员合作使用该设备。脉冲激光系统，如根据该奖项购买的系统，允许化学家以有趣的方式探测物质。 化学反应和分子过程（例如碰撞能量交换）可以通过逐个碰撞的细节进行研究。 有了这种详细程度，化学家可以建立物理模型来描述化学和分子事件，这些事件可以推广到尚未研究的化学系统。 这笔赠款提供的基础设施将用于教学和培训广泛的年轻科学家，在重要的，尖端的，实验方法。

With support from the Chemistry Research Instrumentation and Facilities: Multiuser program (CRIF:MU), the Department of Chemistry at Brigham Young University will acquire two optical parametric oscillator (OPO) laser systems for a new shared laser facility. The laser systems will be used by chemistry department researchers (faculty, graduate and undergraduate researchers) to study a number of problems in the chemical sciences. These include: (1) photochemical dynamics of organometallic species and retinal; (2) the gas-phase structure and bonding of supramolecular ions; (3) gas-phase radical kinetics via cavity ring-down spectroscopy; and (4) ro-vibrational energy transfer in gas-phase species. The laser systems will be used by large numbers of undergraduate and graduate students, both in research as well as in the laboratory curriculum. Access to the instrument will be widened, via a university program aimed at high school students from underrepresented groups. High school students in the outreach program will visit the laboratory as a part of an enrichment program, and some students will use the equipment in collaboration with BYU undergraduate and graduate student researchers.Pulsed laser systems, like the one purchased under this award, allow chemists to probe matter in interesting ways. Chemical reactions and molecular processes (e.g. collisional exchange of energy) can be studied with collision-by-collision detail. With this level of detail, chemists can build physical models to describe chemical and molecular events which can be generalized to as-yet-unstudied chemical systems. The infrastructure made available with this grant will be used in teaching and training a broad range of young scientists, in important, cutting-edge, experimental methods.
