The first set of experimentally determined C−NO bond homolytic and heterolytic dissociation enthalpies in solution is derived by using direct titration calorimetry combined with appropriate electrode potentials through thermodynamic cycles. The homolytic bond dissociation energy scale (BDEs) of the corresponding C−NO bonds in the gas phase was also calculated at the MP2/6-311+G**//B3LYP/6-31G* level
通过使用直接滴定热法结合适当的电势通过热力学循环,得出溶液中第一组实验确定的C-NO键的均质和异质解离焓。在MP2 / 6-311 + G ** // B3LYP / 6-31G *和BP86 / 6-31G *的水平下,还计算了气相中相应C-NO键的均相键解离能级(BDE)。 // B3LYP / 6-31G *出于比较目的的理论水平。使用C-NO和S-NO键的热力学参数来预测NO在乙腈溶液中从C-亚硝基底物转移到硫醇的趋势。
