生成熱計算,ΔHT是out文件的哪一項數(shù)據(jù)?
|
|||||
|
ΔE0 is the change in total energy between the products and the reactants at 0 K; ΔZPE is the difference between the zero-point energies(ZPE)of the products and the reactants; and ΔHT is thermal correction from 0 to 298 K. 不清楚的是thermal correction from 0 to 298 K ΔHT到底在out文件中指的是哪個數(shù)據(jù)?請大家指導(dǎo)! CH4的ΔHT為10.03kj/mol或者0.00381Hartree 我所計算所得為 ------------------- - Thermochemistry - ------------------- Temperature 298.150 Kelvin. Pressure 1.00000 Atm.
