利用高场核磁共振,我们已经确定了六亚甲基三过氧二胺(HMTD)的核四极相互作用的大小,据称HMTD是2005年7月伦敦爆炸案中使用的炸药。实验测得的四极耦合常数为5.334 MHz,与量子化学计算结果符合得很好。预测的单个零场跃迁频率应该位于14N核四极共振(NQR)谱中相对较空的部分;自旋弛豫速率相当快。版权所有©2007 John Wiley&Sons,Ltd.
Using high‐field NMR, we have determined the magnitude of the nuclear quadrupole interaction in hexamethylene triperoxide diamine (HMTD), the explosive allegedly used in the London bombings of July 2005. The experimental quadrupolar coupling constant, 5.334 MHz, is in good agreement with quantum chemical calculations. The predicted single zero‐field transition frequency should lie in a relatively empty part of the14N nuclear quadrupole resonance (NQR) spectrum; the spin relaxation rate is reasonably fast.
