Professor Terry Gullion of West Virginia University is supported by the Experimental Physical Chemistry program to further develop solid state NMR methods applied to amorphous solids. The systems to be studied include molecularly doped polymers relevant to xerography. The PI is coinventor of REAPDOR and REDOR methods and in this proposal he will further enhance the utility of these methods. For REAPDOR, he proposes to derive a universal calibration curve so that costly quantum calculations are not necessary for the interpretation of the signals. Development of NMR methods affords opportunities to study amorphous solids, which are otherwise difficult to study. Once the field matures, the methods have the potential to be applied broadly to problems in solid state physics, chemistry and materials science. The application here, the structure of molecularly doped polymers, is relevant to xerography.

西弗吉尼亚大学的特里·古翁教授得到了实验物理化学计划的支持，以进一步开发用于无定形固体的固态NMR方法。 要研究的系统包括与Xerography相关的分子掺杂聚合物。 PI是Reapdor和Rebor方法的共同介绍，在此提案中，他将进一步增强这些方法的实用性。 对于Reapdor，他提议得出通用校准曲线，以便对信号的解释不需要昂贵的量子计算。 NMR方法的开发提供了研究非晶固体的机会，否则这些固体很难研究。 一旦田地成熟，这些方法就有可能广泛应用于固态物理，化学和材料科学的问题。 这里的应用是分子掺杂聚合物的结构，与轴学有关。
