Presidential Young Investigator/High Resolution Laser Spectroscopy of Clusters

Blake教授在实验物理化学项目的支持下，正在开发创新的激光光谱技术，用于研究极端宇宙化学和人为环境下的化学过程，如分子云、行星大气、等离子沉积室和多相催化容器。实验室和遥感项目都在计划之中。这项研究得到了总统青年研究者奖（PYI）的支持。一个特别强调的领域是光谱响应和化学反应的原子和分子簇的研究，在小分子和宏观样品之间的中间尺寸。冷却射流膨胀或离子阱中的团簇和团簇化学正在使用各种技术进行研究，包括远红外亚多普勒激光边带光谱、光泵浦红外荧光、时间分辨泵浦/探针实验和共振电离质谱。宇宙化学搜索将在不同的天文台进行，以确定在实验室中确定的光谱特征。

Professor Blake with support from the Experimental Physical Chemistry Program is developing innovative laser spectroscopic techniques for the investigation of chemical processes within extreme cosmochemical and man-made environments such as molecular clouds, planetary atmospheres, plasma deposition chambers, and heterogeneous catalysis vessels. Both laboratory and remote sensing programs are planned. This research is supported by a Presidential Young Investigator Award (PYI). A particular area of emphasis is the study of the spectral response and chemical reactivity of atomic and molecular clusters that are intermediate in size between small molecules and macroscopic samples. Clusters and cluster chemistry in cooled jet expansions or ion traps are being examined using various techniques, including sub-Doppler laser sideband spectroscopy in the far-infrared, optically pumped infrared fluorescence, time-resolved pump/probe experiments, and resonance ionization mass spectrometry. Cosmochemical searches will be made at various observatories for spectral features identified in the laboratory.
