dc.description.abstract | Despite extensive studies on the isomer species formed by photodissociation of haloalkanes in solution, the molecular structure of the precursor of the isomer, which is often assumed to be a vibrationally hot isomer formed from the radical pair, and its in-cage isomerization mechanism remain elusive. Here, the structural dynamics of CH2I2 upon 267 nm photoexcitation in methanol were probed with femtosecond X-ray solution scattering at an X-ray free-electron laser. The determined molecular structure of the transiently formed species that converts to the CH2I-I isomer has the I-I distance of 4.17 angstrom, which is longer than that of the isomer (3.15 angstrom) by more than 1.0 angstrom and the mean-squared displacement of 0.45 angstrom(2), which is about 100 times larger than those of typical regular chemical bonds. These unusual structural characteristics are consistent with either a vibrationally hot form of the CH2I-I isomer or the loosely-bound radical pair (CH2IMIDLINE HORIZONTAL ELLIPSISI). | - |
