The vibrational energy levels of the jet-cooled GeCH and GeCD radicals have been studied by a combination of laser-induced fluorescence and wavelength-resolved emission techniques. The radicals were produced in a pulsed electric discharge free jet expansion using methyltrichlorogermane and tetramethylgermane-d12 precursors. A re-examination of the weaker hot bands in the LIF spectrum has provided a
通过结合激光诱导荧光和波长分辨发射技术,研究了喷射冷却的 GeCH 和 GeCD 自由基的振动能级。使用甲基三氯锗烷和四甲基锗烷-d12 前体在脉冲放电自由射流膨胀中产生自由基。对 LIF 谱中较弱的热带的重新检查提供了对上能级能级的更完整的振动分析。分析了通过泵浦每个同位素的几个波段获得的单振动能级发射光谱,以提供关于零点能级以上高达 3000 cm-1 的低位基态振动能级的信息。这些分子在具有相同 P 值但相差一个单位 v2 的振动能级之间发生强烈的相互作用;Northrup 和 Sears [Mol。物理。71, 45 (1990)] 并且方便地称为“西尔斯共振”。GeCH 的光谱被进一步复杂化...
