    • The triplet-triplet absorption of TPM was not reported, however, that of diphenylmethane appeared in the visible region as reported in: Fujiwara, M.; Yamasaki, A. J. Chem. Soc., Faraday Trans. 1998, 94, 2525. The triplet state of TPM would also appear in the visible region by analogy with diphenylmethane, however, significant absorption was not observed in the transient absorption spectra. We concluded that the triplet state formation is negligible. In addition, if the triplet state absorbed the second photon, TPM would be ionized, however, a cation radical was not observed.

    • The time profile at 230 nm has an instrumental response limited rise. It is reasonable to assume the instantaneous hot TPM formation due to the fast internal conversion
