Turgay Uzer is supported by a grant from the Theoretical and Computational Chemistry Program to continue his research on Rydberg State Dynamics in Atoms and Molecules. Uzer will study the dynamics of Rydberg states in atoms and molecules using classical and quantum approaches. He will study the formation of very high molecular Rydberg states as related to zero-electron-kinetic-energy (ZEKE) spectroscopy and the synthesis of nonspreading wavepackets in atoms. The research will rely heavily on the progress he has recently made in the theory of atomic and molecular Rydberg states perturbed by external fields - especially in problems involving Coriolis forces.ZEKE spectroscopy has matured into a very high resolution spectroscopy for the study of short lived intermediates in chemical reactions. It has even yielded the first direct spectroscopic data on elusive transition states of chemical reactions. It also provides measurement to a very high degree of accuracy and at a resolution three orders of magnitude better than other major techniques such as photoelectron spectroscopy. Uzer's research will shed new light on the interpretation and potential applications of this powerful spectroscopic technique.

图尔盖·乌泽尔得到了理论和计算化学计划的资助，继续他对原子和分子中里德堡态动力学的研究。乌泽尔将使用经典和量子方法研究原子和分子中里德堡态的动力学。他将研究与零电子动能(Zeke)光谱学有关的超高分子里德堡态的形成，以及原子中非扩散波包的合成。这项研究将在很大程度上依赖于他最近在受外场扰动的原子和分子里德堡态理论方面取得的进展-特别是在涉及科里奥利力的问题上。ZEKE光谱学已经成熟为研究化学反应中短寿命中间体的非常高分辨率的光谱学。它甚至获得了有关化学反应难以捉摸的过渡态的第一批直接光谱数据。它还提供了非常高精度的测量，分辨率比其他主要技术，如光电子光谱学高出三个数量级。乌泽尔的研究将为这项强大的光谱技术的解释和潜在应用提供新的线索。
