Abstract

An original scale for the reducibility of multiple bonds is established through G4 theoretical calculations in two steps: 1) comparing the gas heats of formation (Δ_fH°) derived from G4 theoretical calculations with experimental values from NIST and ATcT, and 2) using the calculated Δ_fH° (G4) to determine the hydrogenation enthalpies (Δ_H2H°). A rationalization of these values is performed through statistical analysis.

基于G4计算的多键可约性热力学尺度。

通过G4理论计算建立了多键还原性的原始尺度，分两步：1)将G4理论计算得到的气体生成热（ΔfH°）与NIST和ATcT的实验值进行比较，2)利用计算得到的ΔfH°（G4）确定加氢焓（ΔH2H°）。通过统计分析使这些值合理化。
