作者在高于110 GPa的压力下用高于2000 K的激光加热合成了聚合氮。为了证明它的立方角（cg）结构，作者已经生长出在大衍射角下产生强反射的单晶。作者用一种特殊的金刚石砧座在2 θ =35度范围内发现了9个峰。所有的峰都符合cg-N结构。作者检查了垫圈材料和加热器的各种组合，以研究热氮与这些材料或金刚石砧反应的聚合氮副产物的可能污染，并发现情况并非如此。(c)2007年，美国物理学会。
The authors synthesized polymeric nitrogen at pressures above 110 GPa with laser heating above 2000 K. To prove its cubic gauche (cg) structure, the authors have grown single crystals which produced strong reflections at large diffraction angles. The authors found nine peaks in the 2 Theta=35 degrees range with a special diamond anvil cell. All of the peaks agree with the cg-N structure. The authors checked various combinations of gasket materials and heaters to study possible contamination of the polymeric nitrogen by products of the reaction of the hot nitrogen with these materials or diamond anvils, and found that this is not the case.
