identified based on isotope labeled experiments and density functional calculations. For both Y and La atom reactions with H2O, the major reaction products are the HMOH, MO and M(OH)2 (M=Y and La) molecules. In addition, HMO and HM(OH)2 were produced on matrix sample annealing or UV broadband photolysis. Evidence is also presented for the formation of the HYOH+ species. The potential energy surfaces for the
使用基质隔离FTIR光谱和密度泛函计算研究了激光烧蚀的Y和La原子与
水分子的反应。基于同位素标记的实验和密度泛函计算,确定了反应产物。对于Y和La原子与H 2 O的反应,主要反应产物是HMOH,MO和M(OH)2(M = Y和La)分子。此外,HMO和HM(OH)2是通过基质样品退火或UV宽带光解法生产的。还提供了有关HYOH +物种形成的证据。已计算出Y,La + H 2 O反应的势能面以解释反应机理。
