【摘要】

：

质谱成像广泛应用于材料，生物，药学等领域的研究.目前广泛使用的质谱成像方法为SIMS(二次离子质谱)和MALDI(基质辅助激光解吸电离飞行时间质谱).SIMS的空间分辨率可达亚微米，但仅能获得小质量的样品碎片成像信息(m/z＜500)；MALDI可以得到大质量(高达105Da)母体离子，但由于基质效应，该方法的空间分辨率仅能达到微米级别，难于用于研究微小尺寸样品(如单细胞).

水在C(010)态的光解动力学

水分子的光解动力学研究过去三十年取得了极大的进展，尤其是在转动态分辨的水平上揭示了不同电子态上水分子的绝热和非绝热的解离动力学过程。水的C态是束缚态，寿命较长，是第一个可以观测到转动吸收谱的电子态，在其上的解离动力学显示出两个非绝热解离通道。转动量子数Ka(JKaKc)控制着这两个非绝热解离通道的竞争。
