for ligand stabilized complexes and as isolated molecules under matrix isolation conditions. Here, the new molecular products of the reactions of laser‐ablated U and Th atoms with HCl and with HBr, namely HUCl, HUBr and HThCl, HThBr, based on their mid and far infrared spectra in solid argon, are reported. The assignment of these species is based on the close agreement between observed and calculated
氢化铀和or被称为配体稳定的复合物的官能团,在基质分离条件下为分离的分子。在此,根据固体氩气的中红外和远红外光谱,报道了激光烧蚀的U和Th原子与HCl和HBr反应的新分子产物,即HUCl,HUBr和HThCl,HThBr。这些种类的分配基于观察到的和计算出的振动频率之间的紧密一致。在1404.6和323.8 cm -1处分别观察到HUCl的H-U和U- 35 Cl拉伸模式。代替地,使用DC1形成DUC1在1003.1和314.7cm -1处给出吸收带。HThCl的对应谱带为1483.8(H-Th)和1058.0(D-Th),以及分别为340.3和335.8 cm -1(Th- 35 Cl)。在1410.6cm -1处观察到HUBr,并且从HUC1算出的BP86位移为6.2cm -1,具有极好的一致性。由于较少的带负电性的取代基从U键中去除的电荷较少,因此UH的拉伸频率从1383.1(HUF),1404
