Coordination of Deprotonated Ferrous Heme with CO and O<sub>2</sub> in the Gas Phase: Influence of Spin-Orbit Splitting and Charge Open
The ligation of 4-coordinated ferrous heme has been investigated in the gas phase using singly deprotonated heme anions to act as a model for neutral heme. The equilibrium of dioxygen and carbon monoxide ligated to deprotonated heme was ob…

Consistent characterization of the electronic ground state of iron(<span>ii</span>) phthalocyanine from valence and core–shell electron spectroscopy Open
We studied the iron( ii ) phthalocyanine molecule in the gas-phase and characterized its electronic ground-state through consistent corpus of experimental electronic spectra simulated by DFT and charge-transfer-multiplet calculations.

Heme ligation in the gas phase Open
This review summarizes the state-of-the-art knowledge of heme ligation in the gas phase. The unique aspect of the gas phase approach is to allow a step-by-step ligation of heme and thus enables the analysis of the properties of -four, -fiv…

Time-Resolved Observation of the Solvation Dynamics of a Rydberg Excited Molecule Deposited on an Argon Cluster. II. DABCO<sup>☆</sup> at Long Time Delays Open
The real-time dynamics of DABCO-argon clusters is investigated in a femtosecond pump-probe experiment where the pump excites DABCO to the S1 state within the argon cluster. The probe operates by photoionization and documents the energy and…
