查询词典 hydrogen iodide

Comparing with the result of methyl iodide in intense laser field, some differences are observed:(1) at the same laser field intensity, the highest charged fragment ion of methyl bromide was Br(superscript 3+), lower than I(superscript 6+) of methyl iodide;(2) the dehydrogenation channel was observed in the multiphoton dissociation or Coulomb explosion of methyl bromide, but was not observed in the case of methyl iodide;(3) HBr(superscript +) was observed, but there was no similar channel in the case of methyl iodide;(4) for methyl bromide, the valid charge distance of Coulomb explosion increases with the product of p and q; while in the case of methyl iodide, the distance remained almost the same;(5) the producing channel of CH(superscript + subscript m)(m=0, 1, 2) is different from the ionization-dissociation of methyl iodide in which the stepwise dissociation of CH3(superscript +) was thought to be the main channel, CH(superscript + subscript m)(m=0, 1, 2) of methyl bromide are mainly from the products of the direct dissociation of the dehydrogenated parent ions instead of the stepwise dissociation of CH3(superscript +).

与碘甲烷在强场中的实验结果对比发现：(1)在相同的激光场强下，碘甲烷电离解离的最高价碎片离子为I(上标 6+)而溴甲烷为Br(上标 3+)；(2)溴甲烷质谱中存在母体离子的脱氢产物CHBr和CHBr(上标 2+)，而对于碘甲烷，没有检测到这些通道，C-I键首先断开；(3)质谱中存在H^79Br和H^81Br，而碘甲烷的电离解离中不存在HI产物；(4)溴甲烷库仑两体爆炸的有效电荷间距随着两碎片电荷乘积的增大而增大，而对于碘甲烷此间距几乎不随电荷乘积变化；(5)CH(m=0， 1， 2)的主要生成通道可能与碘甲烷不同，不是来自CH3的顺序脱氢，而是来自脱氢母体离子的直接解离。
