Purchase of a High Speed Transient Digitizer and a Low Temperature Dewar for Elucidating the Excited State Properties of Novel Oligonuclear and Mixed-Metal Complexes

化学仪器项目的拨款将用于购买高速瞬态数字化仪。该仪器将用于在很短的时间内收集高能量（激发态）分子的数据，这些分子是由于激光吸收光而产生的，持续时间不到一微秒。在与太阳能转换有关的化学过程中，了解这类物质的性质是很重要的。该仪器将主要用于混合金属和低聚物配合物的光物理研究。它将用于确定激发态寿命、活化能和激发态复合物的瞬态衰减谱。

This grant from the Chemical Instrumentation Program will be used to purchase a high-speed transient digitizer. The instrument will be used to collect data over very short time periods on high energy (excited state) molecules which are produced as the result of the absorption of light from a laser and which persist for less than a microsecond. An understanding of the properties of such species is important in chemical processes related to solar energy conversion. The instrumentation will be used primarily in studies of the photophysics of mixed-metal and oligimer complexes. It will be used to determine excited state lifetimes, activation energies, and transient decay spectra of excited state complexes.
