摘要提案题目：用于振动和频率产生光谱的扩展波长脉冲激光系统的开发提案号：CTS - 0520985首席研究员：Robb M. WinterInstitution：南达科他州矿业与技术分析学院（决策依据）：该项目将开发所需的基础设施，以促进南达科他州矿业与技术学院和400英里半径内的其他机构的先进激光光谱研究。将开发用于执行振动和频率产生光谱学的设备，包括以下目标：1)开发皮秒激光脉冲波长扩展到中红外范围；2)光谱仪的建设；3)与时间相关荧光光谱仪的集成。该设施将允许确定分子结构的空间依赖性、时间依赖性和化学依赖性。使用新的光谱仪，可以对衬底和体相之间的界面进行特殊研究，这对于开发对薄膜制造、固化和粘附的更基本的理解将具有很高的价值。界面上分子功能的相互作用和界面动力学影响这些相互作用的机制都将被研究。用于涂料和纳米颗粒的聚合物薄膜将是研究的重点。新设施将为物理学、电气工程、分析化学和其他学科的本科生和研究生提供新的教育机会。大力加强跨学科研究。为妇女和印第安学生提供特殊机会的项目已经到位。建立了一个有效的REU程序。该工具将成为一个区域设施，由一些对拥有这种先进能力非常感兴趣的机构使用。

AbstractProposal Title: Development of an Extended Wavelength Pulsed Laser System for Vibrational Sum-Frequency Generation SpectroscopyProposal Number: CTS - 0520985Principal Investigator: Robb M. WinterInstitution: South Dakota School of Mines and Technology Analysis (rationale for decision): The project will develop the infrastructure needed to foster advanced laser spectroscopy research at the South Dakota School of Mines and Technology and other institutions within a 400-mile radius. A facility for performing vibrational sum-frequency generation spectroscopy will be developed including the following objectives: 1) development of a picosecond laser pulse wavelength extension into mid-infrared range; 2) construction of a spectrometer; and 3) integration of the new instrument with a time-correlated fluorescence spectrometer. The facility will allow the spatial dependency, time dependency, and chemical dependency of molecular structures to be determined. Special investigations of the interface between a substrate and a bulk phase will be possible with the new spectrometer, which will be highly valuable in developing a more fundamental understanding of film fabrication, curing, and adhesion. Both the interactions of molecular functionalities at interfaces and the mechanisms through which interface dynamics influence these interactions will be investigated. Polymeric films used for coatings and nanoparticles will be important emphases in the research. The new facility will provide new educational opportunities for undergraduate and graduate students from physics, electrical engineering, analytical chemistry, and other disciplines. Interdisciplinary research efforts will be strongly enhanced. Programs are in place that provide special opportunities for women and Native American students. An effective REU program has been established. The instrument will become a regional facility which will be utilized by a number of institutions that are strongly interested in having this advanced capability.
