    • We have measured the transient absorption spectrum of PB after the photoexcitation at 640 nm with subpicosecond time resolution. The hole dynamics of PB indicates that the chemical inhomogeneity that persists more than several ps (for example, isomers of slow isomerization) contributes little to the bandwidth of the absorption spectrum

    • In this respect, there are some ambiguities in the analysis of the bandwidth of the CN stretching mode given in Ref. 7, since we did not take into account the spectrum contamination and the line broadening mechanism peculiar to the resonance condition. The overlap with bands 2 and 3 should also affect estimation of the peak position in Ref. 7. However, we consider it does not affect the qualitative discussions there
