A transient photoinduced reflection difference spectrum of a polymeric single crystal of 2,4-hexadiyn-1,6-di-p-toluenesulphonate was measured at room temperature. The recombination of the photoexcited species is dominated by one-dimensional random-walk kinetics which can be expressed by a single error function, erf[(τ/t)1/2]with τ = 0.75 ± 0.25 μs, over the delay time between 0 and 180 μs.
