Long & Medium-Term Research: Electronic Band Structures and Chemical Bonding in Mixed Organic/Organometallic Charge Transfer Salts and Phosphate Tungsten Bronzes This award recommendation is made under the Program for Long & Medium-Term Research at Foreign Centers of Excellence. The program seeks to enable US scientists and engineers to conduct long-term research abroad at research institutions of proven excellence. Awards provide opportunities for the conduct of joint research, and the use of unique or comple- mentary facilities, expertise and experimental conditions in foreign countries. This award is for a proposal sponsored by Dr. Malcolm H. Chisholm to support a 12 month post-doctoral visit by Dr. James D. Martin to France to work with Dr. Enric Canadell of the Universit de Paris-Sud on "Electronic Band Structures and Chemical Bonding in Mixed Organic/Organometallic Charge Transfer Salts and Phosphate Tungsten Bronzes." The synthesis of new solid state materials with predictable physical properties is presently a major challenge for chemists. Central to achieving this goal is an understanding of how electronic structures are related to specific crystal structures of a material. Dr. Martin proposes to examine the electronic structures of organic/organometallic charge transfer salts and phosphate tungsten bronzes. Calculation of the band structures and Fermi surfaces of the respective solids is expected to provide fundamental understanding of the relationships between crystal structures and physical properties. Large and complex unit cells of solids make the consideration of all orbital interactions quite difficult. For this reason, the perspective of "molecules in solids" will be used to identify features of the crystal structures essential for the description of specific electronic properties. The award recommendation provides funds to cover, as appropriate, international travel, local travel abroad, stipend, dependents' allowance if applicable, and a flat administrative allowance of $250 for the U.S. home institution.

长期和中期研究：混合有机/有机金属电荷转移盐和磷酸盐钨古铜色的电子带结构和化学键合在外国卓越中心的长期和中期研究计划下提出。 该计划旨在使美国的科学家和工程师能够在公认的卓越研究机构向国外进行长期研究。 奖项为进行联合研究的进行提供了机会，以及在国外使用独特或组成的设施，专业知识和实验条件。 该奖项是由Malcolm H. Chisholm博士赞助的一项提案，以支持James D. Martin博士向法国进行12个月的访问，与Paris de Paris-Sud的Enric Canadell博士一起在“电子带结构和化学键上进行化学键合成有机/有机/有机金属收费转移盐和磷酸盐底型隆隆布氏灌注”。 目前，具有可预测的物理特性的新固态材料的合成是化学家的主要挑战。 实现这一目标的核心是了解电子结构与材料的特定晶体结构的关系。 Martin博士建议检查有机/有机金属电荷转移盐和磷酸盐钨青铜的电子结构。 预计各个固体的带结构和费米表面的计算将提供对晶体结构与物理特性之间关系的基本理解。 固体的大而复杂的单元细胞使所有轨道相互作用都非常困难。 因此，“固体分子”的视角将用于识别描述特定电子特性所必需的晶体结构的特征。 该奖项建议提供资金，以供应供应供应，以供应供应，以供应，如果适用，津贴，津贴，津贴，抚养人的津贴以及美国家庭机构的统一行政津贴。
