Kinetic curves obtained for C₂H₂, C₆H₂, C₄H₂, and C₄H₁₀. Note: the area of the (ν₄) absorption feature of C₄H₂ cannot be deconvoluted from the contribution of the (ν₁) absorption feature of C₄H₄. Thus, the combined area is used for the integration. The modulus of absorbance is taken for C₂H₂ and C₄H₂ consumed in the experiments. This allows for the direct comparison with produced species. The ordinate axis is presented as a logarithm of 10.
