Isocyanate Formation from Reactions of Early Lanthanide Metal Atoms with NO and CO in Solid Argon
journal contribution
posted on 2017-10-03, 00:00 authored by Jiwen Jian, Qingnan Zhang, Xuan Wu, Mingfei ZhouThe
reactions of early lanthanide metal atoms (Ce, Pr, and Nd)
with carbon monoxide and nitric oxide mixtures are studied by infrared
absorption spectroscopy in solid argon. The reaction intermediates
and products are identified via isotopic substitution as well as theoretical
frequency calculations. The results show that the reactions proceed
with the initial formation of inserted NLnO molecules, which subsequently
react with CO to form the NLnO(CO) complexes on annealing. The NLnO(CO)
complexes further isomerize to the more stable isocyanate OLnNCO species
under UV light excitation.
