摘要

固体物质的核四极共振频率主要由原子核及核外电场梯度决定

对于同种原子核

核四极共振频率主要由核外电场梯度决定.在不同水平下使用H artree-Fock方程计算了高能炸药奥克托金(HM X)分子环上氮原子的核四极耦合常数、核外电场梯度以及电场梯度张量不对称参数

研究了HM X分子结构与核四极共振参数之间的关系

并将计算值与试验值进行了比较分析.结果表明:在D 95及D 95v1水平上

理论值与试验值符合的较好

为类似结构物质核四极共振频率的确定提供了一种方法.

Abstract

The NQR frequency at resonance of solid substance is determined by the atomic nucleus and the electricity field gradient outside.For same atomic nucleus

the NQR frequencies are primarily determined by the electricity field gradient outside the atomic nucleus.The nuclear quadruple resonance frequency

the nuclear quadrupole coupling constant

and the electricity field gradient of nitrogen atom on the ring of HMX were calculated by Hartree-Fock equation at different levels.The relationship between molecule structure of HMX and nuclear quadrupole resonance frequency was described

and the calculated value was compared and analyzed with the experiment value.The study shows that the experimental value is properly accordance with the calculated value at the level of D95 and D95v1.This study provides a method for determining the NQR frequencies of substance with similar structures.
