molecular complexes of AlBr3 with amines such as (CH3)3N, C5H5N, C6H5NH2, and (C6H5)2NH. All the 81Br resonance lines were found in the frequency range of 78–86 MHz at room temperature except for AlBr3·2C5H5N. From the Zeeman analysis, it was proved that AlBr3·2C5H5N should be expressed with the molecular formula 2AlBr3·4C5H5N and contains cation species AlBr2(C5H5N)4+ with two 81Br resonance lines near
我们观察到 AlBr3 与胺(如 (CH3)3N、C5H5N、C6H5NH2 和 (C6H5)2NH)的几种分子复合物的 81Br NQR。除 AlBr3·2C5H5N 外,所有 81Br 共振线均在室温下的 78-86 MHz 频率范围内发现。塞曼分析证明,AlBr3·2C5H5N应用分子式2AlBr3·4C5H5N表示,并含有在70 MHz附近具有两条81Br共振线的阳离子物质AlBr2(C5H5N)4+和具有4条81Br共振线的阴离子物质AlBr4−接近 80 MHz。由于整个分子的旋转受阻,AlBr3·(CH3)3N的两条81Br共振线在约40℃时消失。AlBr2(C5H5N)4+ 的下方两条 81Br 共振线具有正温度系数。
