    • TPA measurements at redder wavelengths such as 650 nm showed a longer time constant offset having an amplitude of as much as 25% of the TPA signal. This is believed to be due either to photoproducts formed in the l-methylnaphthalene and/or longer lived transient absorptions of the parent compound.

    • The cutoff at 550 nm for the nanosecond difference absorption spectrum is experimentally imposed because of the onset of emission on these time scales at longer wavelengths.

    • III - (dmb π)) in nature. This implies that the neutral ligand participating in the transition is not the ligand involved in the initial MLCT absorption of 400 nm light. In the limit of weak coupling between excited states in this molecule, it is reasonable to expect that there will be an attenuation of vibrational relaxation that is necessary in the excited-state probed by the 650 nm absorption.

    • note
    • The apparent spectral shift in the initial evolution of the transient full spectral data is due to the ∼300 fs temporal chirp (480-650 nm) within the white light probe (see Experimental Section).
