The molecule images are rendered by Indigo-depict. The find function is based on the complete Species Dictionary entries for the appropriate version of the ATcT TN. The reorganization of the website was developed and implemented by David H. Note that an uncertainty of ± 0.000 kJ/mol indicates that the estimated uncertainty is < ± 0.000 5 kJ/mol. The listed uncertainties correspond to estimated 95% confidence limits, as customary in thermochemistry (see, for example, Ruscic ). The aggregate state is given in parentheses following the formula, such as: g - gas-phase, cr - crystal, l - liquid, etc. Uncertainty Quantification in Thermochemistry, Benchmarking Electronic Structure Computations, and Active Thermochemical Tables.

Most Influential reactions involving F (g, 2P1/2) Please note: The list, which is based on a hat (projection) matrix analysis, is limited to no more than 20 largest influences. The correlation coefficient is a number from -1 to 1, with 1 representing perfectly correlated species, -1 representing perfectly anti-correlated species, and 0 representing perfectly uncorrelated species. Please note: The correlation coefficients are obtained by renormalizing the off-diagonal elements of the covariance matrix by the corresponding variances. Top 10 species with enthalpies of formation correlated to the Δ fH° of F (g, 2P1/2) The quoted uncertainty is the a priori uncertainty used as input when constructing the initial Thermochemical Network, and corresponds either to the value proposed by the original authors or to our estimate if an additional multiplier is given in parentheses immediately after the prior uncertainty, it corresponds to the factor by which the prior uncertainty needed to be multiplied during the ATcT analysis in order to make that particular measurement consistent with the prevailing knowledge contained in the Thermochemical Network.īytautas 2007b, Bytautas 2007a, Bytautas 2007, Bytautas 2009 The Measured Quantity is normaly given in the original units in cases where we have reinterpreted the original measurement, the listed value may differ from that given by the authors. The Reference acts as a further link to the relevant references and notes for the measurement. Please note: The list is limited to 20 most important contributors or, if less, a number sufficient to account for 90% of the provenance. Top contributors to the provenance of Δ fH° of F (g, 2P1/2) The 20 contributors listed below account only for 64.5% of the provenance of Δ fH° of F (g, 2P1/2).Ī total of 71 contributors would be needed to account for 90% of the provenance. ![]()
