Fit for the reaction m- + HD  →  p-D₂H⁺ + o-D₂. The reaction being endothermic by 206 K, we have multiplied the coefficients by e^206/T_kin. For the lowest temperatures the original reaction rates were zeroed and cannot be retrieved. The first non-zeroed rates are not fitted because the endothermic correction will dominate (see Fig. C.2). Data are in red, fit in green. The fit gives the first two coefficients, α and β.
