我们给出了光谱和结构证据，证明了在将富氮混合物压缩到5.5 Gpa和10 Gpa后，形成了均匀的立方-N-2类非晶态固体和无公度六方(P6(3)22)包裹体(N-2)(12)D-2。在(N-2)(12)D-2中，从蓝移、不连续的变化以及D-2振子没有翻转到70 GPa中明显地表现出强烈的排斥耦合-所有这些都与纯D-2和其他包合物形成了鲜明的对比。这种排斥相互作用是由于观察到的不公度结构和巨大的内压造成的。(C)2011年美国物理研究所。[DOI：10.1063/1.3533957]
We present spectral and structural evidences for the formation of a homogeneous cubic delta-N-2-like, noncrystalline solid and an incommensuratelike hexagonal (P6(3)22) inclusion compound (N-2)(12)D-2, formed by compressing a nitrogen-rich mixture to 5.5 and 10 GPa, respectively. A strong repulsive coupling in (N-2)(12)D-2 is evident from a blue shift, discontinuous changes, and the absence of turnover of the D-2 vibron to 70 GPa-all in sharp contrast to both pure D-2 and other inclusion compounds. This repulsive interaction is responsible to the observed incommensuratelike structure and large internal pressure. (C) 2011 American Institute of Physics. [doi:10.1063/1.3533957]
