9312952 Rodriguez In this project in the Physical Chemistry Program of the Chemistry Division Prof. Art Rodriguez of East Carolina University will carry out a series of NMR measurements of the carbon-13 spin-relaxation time of buckminsterfullerene in a number of organic solvents having different molecular properties. The measurements will be made as function of temperature and magnetic field strength for each of the solvents. %%% Research on the properties of fullerenes is at the forefront of chemistry. Most of the attention has been given so far to the synthesis and properties of individual fullerene molecules and the data base for fullerene properties in solution is very sparse. The special fullerene to be studied is buckminsterfullerene, a nearly spherical compound composed of 60 carbon atoms. The experimental data obtained will be used to test a simplified model for molecular reorientation in liquid solutions. ***

9312952罗德里格斯在化学系物理化学项目中，东卡罗来纳大学的阿特·罗德里格斯教授将对巴克明斯特富勒烯在一些不同分子性质的有机溶剂中的碳-13自旋弛豫时间进行一系列核磁共振测量。测量将作为每种溶剂的温度和磁场强度的函数进行。%富勒烯的性质研究处于化学的前沿。到目前为止，大多数注意力都集中在单个富勒烯分子的合成和性质上，而关于富勒烯在溶液中的性质的数据库非常稀少。要研究的特殊富勒烯是巴克明斯特富勒烯，一种由60个碳原子组成的近乎球形的化合物。得到的实验数据将被用来检验一个简化的分子在液体溶液中重新定向的模型。***
