The measured transients for the parent ion and the isobaric fragments, iodine and naphthyl radical, show complex decay profiles with up to four lifetimes in the femto-picosecond time scales. The transients are interpreted as the result of parallel relaxation of the simultaneously excited nσ* and ππ* states of the molecule. While the former leads to dissociation in about 400 fs, the latter converts to lower energy ππ* singlet states at an ultrafast rate (24 fs) followed by intersystem crossing to nearby ππ* triplet states.engAttribution-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nd/4.0/journal article1463-9084https://doi.org/10.1039/C000121jmetadata only accessQuímica física (Química)2307 Química Física
