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Terry Gullion教授得到了实验物理化学计划的支持，以进一步开发应用于无定形固体的固态NMR方法。 待研究的系统包括与静电复印相关的分子掺杂聚合物。 PI是REAPDOR和REDOR方法的共同发明者，在本提案中，他将进一步增强这些方法的实用性。 对于REAPDOR，他建议导出一个通用的校准曲线，这样就不需要昂贵的量子计算来解释信号。 核磁共振方法的发展为研究无定形固体提供了机会，否则很难研究。 一旦该领域成熟，这些方法有可能广泛应用于固体物理，化学和材料科学中的问题。 这里的应用，分子掺杂聚合物的结构，与静电复印有关。
