对于反应: A---BC (reaction complex) -----> AB---C (product complex), 想计算反应的吉布斯自由能垒ΔG,分别优化得到了反应物complex,过渡态complex以及产物complex的结构, 进行Freq计算:
freq计算输出示例:
Zero-point correction= 0.143128 (Hartree/Particle)
Thermal correction to Energy= 0.149580
Thermal correction to Enthalpy= 0.150525
Thermal correction to Gibbs Free Energy= 0.112238
Sum of electronic and zero-point Energies= -344.440134
Sum of electronic and thermal Energies= -344.433681
Sum of electronic and thermal Enthalpies= -344.432737
Sum of electronic and thermal Free Energies= -344.471024
想问一下反应过程ΔG的值是由反应物的最后一项能量值(电子能加上自由能)与过渡态结构对应的相应能量值做差么?
谢谢!
