One-photon mass-analyzed threshold ionization (MATI) spectrum of trans-C(2)H(2)Cl(2) was obtained by using vacuum ultraviolet radiation generated by four-wave mixing in Kr. The ionization energy determined from the position of the 0-0 band in the spectrum was 9.6306 +/- 0.0006 eV. Ten vibrational fundamentals for the cation were identified. The spectrum also displayed abundant overtones and combinations, most of which could be assigned adequately by comparing with the quantum chemical results. It was found that channel interaction was not important for this system. The equilibrium geometry of the cation was estimated through the Franck-Condon fit.
通过使用在氪气中四波混频产生的真空紫外辐射，获得了反式 - C₂H₂Cl₂的单光子质量分析阈值电离（MATI）光谱。由光谱中0 - 0带的位置确定的电离能为9.6306 ± 0.0006电子伏特。确定了阳离子的十个振动基频。光谱还显示出丰富的泛音和组合，通过与量子化学结果比较，其中大部分可以得到充分归属。发现通道相互作用对该系统并不重要。通过弗兰克 - 康登拟合估计了阳离子的平衡几何结构。
