9309467 Whitmire This award from the Chemistry Research Instrumentation Program will assist the Department of Chemistry at Rice University in the purchase of high resolution Mass Spectrometer . This new instrumentation will enhance greatly research in a number of areas including the following: 1) The chemistry of C60 and the higher fullerenes, 2) Synthetic and structural investigations of the catalytic formation of C-C bonds, the use of new thermal or photochemical cycloadditions and the development of new syntheses of nitrogenous substances, 3) The formation of nitrogen- and carbon-centered radicals from azoalkanes, 4) The use of mass spectrometry in the total synthesis of complex natural products, 5) The biosynthesis of natural products, 6) Chemistry of the heavy main group elements. This instrument will replace two old mass spectrometers, one purchased in 1969 and one purchased in 1975. %%% The mass spectrometer is used to measure the precise mass of molecular ions. The fragmentation pattern of the various ions present gives information about the molecular structure of the parent molecules from which the molecular ions evolved. Such information is essential for any modern program of chemical synthesis. ***

9309467 Whitmire 化学研究仪器计划的这一奖项将协助莱斯大学化学系购买高分辨率质谱仪。 这种新仪器将极大地促进许多领域的研究，包括：1）C60和高级富勒烯的化学，2）C-C键催化形成的合成和结构研究，新的热或光化学环加成的使用以及含氮物质新合成的发展，3) 从偶氮烷烃形成氮和碳中心自由基，4) 质谱在全合成中的应用复杂天然产物的研究，5）天然产物的生物合成，6）重主族元素的化学。 该仪器将取代两台旧的质谱仪，一台于 1969 年购买，一台于 1975 年购买。 %%% 质谱仪用于测量分子离子的精确质量。 存在的各种离子的碎裂模式提供了有关分子离子演化的母体分子的分子结构的信息。 这些信息对于任何现代化学合成程序都是必不可少的。 ***
