Here we report the gas-phase action spectrum of tris(2,2′-bypyridine)ruthenium(II) dications, Ru(bipy)32+, recorded over a broad wavelength region from 210 nm to 650 nm. Ions formed by electrospray ionization were thermalized in collisions with hel

Photodissociation of the complex between protonated tryptamine, TryH + , and 18-crown-6 ether (CE) was investigated. Absorption maxima of TryH + and TryH + (CE) are at 249 and 273 nm, respectively. Ions decay exponentially on a microsecond timescale,

Electron-capture induced dissociation of protoporphyrin cations and anions has been studied. The cations captured two electrons in two successive collisions and were converted to the corresponding even-electron anions. About one fifth of the ions los

From blue to red: While four π-conjugated nitrophenolates absorb within a relatively narrow region in solution, they cover the entire visible spectrum when isolated in vacuo (see picture). The work combines gas- and solution-phase spectroscopy and p

Charge-transfer excitations highly depend on the electronic coupling between the donor and acceptor groups. Nitrophenolates are simple examples of charge-transfer systems where the degree of coupling differs between ortho, meta and para isomers. Here

The loss of C(2)H(2) is a low activation energy dissociation channel for anthracene (C(14)H(10)) and acridine (C(13)H(9)N) cations. For the latter ion another prominent fragmentation pathway is the loss of HCN. We have studied these two dissociation

Gas-phase action spectroscopy shows unambiguously that the low-energy absorptions by tetramethylthiotetrathiafulvalene and tetrathianaphthalene cations in solution phase are due to monomers and not π-dimers.
