We report partial absolute cross sections for dissociative electron attachment (DEA) to tetrahydrofuran C₄H₈O. The high sensitivity of the present setup, quantitative DEA spectrometer with time-of-flight analyzer, led to identification of a number of previously unreported fragments (CH₂⁻, OH⁻, CHO⁻, C₄H₅O⁻, C₃H₃⁻) thus revealing complex dissociation dynamics of the...

A comparative study of (poly)ether adducts of alkaline earth iodides – an overview including new compounds

Maudez, William ; Fromm, Katharina M.

In: Zeitschrift für anorganische und allgemeine Chemie, 2012, vol. 638, no. 11, p. 1810–1819

New homoligand and mixed-ligand adducts of the heavier alkaline earth metal (Ca, Sr, Ba) halides with oxygen-donor polyether ligands have been isolated and characterized and are compared with previously obtained compounds of the same class in order to give an overview on structures and properties. Homoligand halide adducts, discussed herein, are [CaI(DME)₃]I (1),...
