Tunable laser photodissociation spectroscopy and photofragment imaging experiments are employed to investigate the spectroscopy and dissociation dynamics of the Mg(benzene) ion-molecule complex. When excited with ultraviolet radiation, Mg(benzene) photodissociates efficiently, producing both Mg and benzene fragments, with branching ratios depending on the wavelength. The wavelength dependence of these processes are similar, with intense resonances at 330 and 241 nm and weaker features at 290 and 258 nm.

At-home self-collection of blood tests, urine samples and anthropometric data through a postal box may facilitate engagement.

These ions are mass-selected and photodissociated with tunable UV-visible lasers. In both cases, photodissociation produces the organic cation as the only fragment via a metal-to-ligand charge-transfer process.

Additional spectroscopy measurements determine the dissociation energy of Fe(benzene). The dissociation energies for Fe(benzene) determined from the threshold for the appearance of the Fe fragment (48.
