The structure, dynamics, phase transitions, chemical reactions and electronic properties of condensed systems at high pressures and other extreme conditions will be investigated using techniques such as Raman spectroscopy and x-ray diffraction. Systems to be investigated include: phase equilibria of oxygen, nitrogen and sulfur, and mixtures of oxygen/nitrogen, carbon monoxide/nitrogen, oxygen/argon; structures of organic and polymeric conducting materials; thermal- and photo-instabilities of simple aromatic molecules at moderate pressures. In addition, internally heated diamond-anvil cells for x-ray diffraction studies at high pressures will be developed.

将使用拉曼光谱和 X 射线衍射等技术研究高压和其他极端条件下凝聚系统的结构、动力学、相变、化学反应和电子特性。 待研究的系统包括：氧、氮和硫的相平衡，以及氧/氮、一氧化碳/氮、氧/氩的混合物；有机和聚合物导电材料的结构；简单芳香分子在中等压力下的热稳定性和光稳定性。 此外，还将开发用于高压下 X 射线衍射研究的内部加热金刚石砧室。
