英文摘要:
In this 2nd chapter of the book Quantum Mechanical Prediction of Thermochemical Data" (ed. Jerzy Cioslowski, Kluwer, 2001; ISBN 0-7923-7077-5), we review the nonempirical computational thermochemistry methods W1 and W2 theory and their variants. The chapter is made available online following a change in publisher E-print policy.
Benchmark thermochemistry of the C_nH_{2n+2} alkane isomers (n=2--8) and performance of DFT and composite ab initio methods for dispersion-driven isomeric equilibria
本文用W_4、W_3.2lite和W_1h理论重新研究了八碳以下直链和支链烷烃的热化学。通过等键和次同键反应获得了"准W4"原子化能。我们在0 K时的最佳原子化能量(kcal/mol)为:1220.04正丁烷,1497.01正戊烷,1774.15正己烷,2051.17正庚烷,2328.30正辛烷,1221.73异丁烷,1498.27异戊烷,1501.01新戊烷,1775.22异己烷,1774.61 3-甲基戊烷,1775.67二异丙基、1777.27新己烷、2052.43异庚烷、2054.41新庚烷、2330.67异辛烷和2330.81六甲基乙烷。我们对$ΔH^\circ_{f,298K}$的最佳估计为:-30.00正丁烷、-34.84正戊烷、-39.84正己烷、-44.74正庚烷、-49.71正辛烷、-32.01异丁烷、-36.49异戊烷、-39.69新戊烷、-41.42异己烷、-40.72 3-甲基戊烷、-42.08二异丙基、-43.77新己烷,-46.43异庚烷、-48.84新庚烷、-53.29异辛烷和-53.68六甲基乙烷。这些是在极好的协议(通常优于1 kJ/mol),在298 K的实验生成热从CCCBDB和/或NIST化学网络图书数据库。然而,在0 K的理论和实验(1.1千卡/摩尔)之间的一个很大的差异观察到只有新戊烷。这种偏差主要是由于在计算0 K CCCBDB值时使…
