MRI-R2: Development of a Cyber-enabled Third Generation Chirped-Pulse Fourier Transform Microwave (CP-FTMW) Spectrometer

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。弗吉尼亚大学的Brooks H. Pate教授、匹兹堡大学的David W. Pratt教授和佛罗里达新学院的Steven T. Shipman教授获得了主要研究和仪器（MRI）项目的这一奖项，他们提交了一份提案，以响应MRI- r2招标，构建用于分子结构测定的第三代啁啾脉冲傅立叶变换微波光谱仪（CP-FTMW）。该仪器将推进微波光谱分析构象柔性分子、分子配合物和化学反应物质（如离子和自由基）。此外，将设计和实现强大的新型双共振技术，利用高速任意波形发生器产生的完全可成形的微波脉冲。这些技术将使利用光谱仪的性能提升来加速光谱分析成为可能，而不仅仅是获取光谱。CP-FTMW技术利用高速数字电子技术的进步，在获得分子旋转光谱方面实现了优异的速度和灵敏度。光谱分析为所研究的分子、离子和自由基提供了详细的结构参数。结构信息是理解化学性质和反应性的必要条件。该光谱仪的开发将培养本科生和研究生如何构建和使用现代仪器。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).With this award from the Major Research and Instrumentation (MRI) program, Professor Brooks H. Pate of the University of Virginia, David W. Pratt of the University of Pittsburgh and Steven T. Shipman of New College of Florida have submitted a proposal in response to the MRI-R2 solicitation to construct a 3rd Generation Chirped-Pulse Fourier Transform Microwave spectrometer (CP-FTMW) for applications in molecular structure determination. The proposed instrument will advance microwave spectroscopy for the analysis of conformational flexible molecules, molecular complexes and chemically reactive species such as ions and radicals. In addition, powerful new double-resonance techniques using fully shapeable microwave pulses produced by a high-speed arbitrary waveform generator will be designed and implemented. These techniques will make it possible to use the spectrometer's performance gains to speed the analysis of spectra, not just the acquisition of spectra. The CP-FTMW technique exploits advances in high-speed digital electronics to achieve excellent speed and sensitivity in obtaining molecular rotational spectra. Analysis of the spectra provides detailed structural parameters for the molecules, ions and radicals under investigation. Structural information is the sine qua non necessary to understand chemical properties and reactivity. The development of this spectrometer will train undergraduate and graduate students in the construction and use of modern instrumentation.
