We present low-energy velocity map photoelectron imaging results for nitromethane anions. The photoelectron spectrum is interpreted with the aid of ab initio theory and Franck-Condon factor calculations. We obtain a new value for the adiabatic electron affinity of nitromethane of (172+/-6) meV and observe the dipole-bound state of nitromethane. The photoelectron angular distributions of the observed features are discussed in the context of threshold laws for photodetachment.
我们展示了硝基甲烷阴离子的低能速度映射光电子成像结果。借助从头算理论和弗兰克 - 康登因子计算对光电子能谱进行了解释。我们得到了硝基甲烷绝热电子亲和势的新值为(172±6)毫电子伏特，并观测到了硝基甲烷的偶极束缚态。在光剥离阈值定律的背景下讨论了所观测特征的光电子角分布。
