Comparison of kp(T) data for molecules HS (mercapto) and CN (cyanogen) used by several groups. The second column of smaller plots shows the deviations of log10kp from the mean values (computed without the Tsuji data). On the right side, the data has been converted to [kJ mol−1] (see Eq. (13)), before computing the deviations from the mean values. The large deviations at small temperatures for the Tsuji (1973) and Sharp & Huebner (1990) data are due to extrapolation errors beyond the valid fit-range. HS is classified as belonging to the group “data disagrees”, and CN to “data disagrees at low temperatures” in our comparison catalogue (Worters et al. 2017) since even without the Tsuji data, there are relatively large differences to the new (Barklem & Collet 2016) data.
