Arbeitsgebiet

 

Synthese von Einkristallen unter schwach hydrothermalen Bedingungen

Synthese von salzartigen Verbindungen der ersten Reihe der Übergangsmetalle mit Schwerpunkt auf Seleniten, Sulfaten und Selenaten des zweiwertigen Kobalts; weiters Ni(II), Cr(III), Mn(II), Mn(III), Mn(IV), u.a.

 

Kristallstruktur- und kristallchemische Untersuchungen an Mineralen  und synthetischen anorganischen Festkörpern

Strukturuntersuchungen mittels Einkristallröntgenbeugung;
ab-initio Strukturbestimmung aus Pulverröntgenbeugungsdaten;
Kristallchemie des Co(II) Ions in Sauerstoffkoordination – Frage des Jahn-Teller Effekts bei Co(II); kristallchemische Untersuchungen an Reihen von isotypen Verbindungen der Übergangsmetalle, z.B. Kieseritgruppe, Vivianitgruppe, synthetische Isotype von Co(II) und Ni(II)

 

UV-VIS-NIR Absorptionsspektroskopie von Mineralen und  synthetischen anorganischen Festkörpern

Mikroskop-Absorptionsspektroskopie an Verbindungen von Übergangsmetallionen mit d3 und d7 Elektronenkonfiguration:
Cr(III), Mn(IV), besonders Co(II). Interpretation und Berechnung von d-d; Übergangsenergien in nicht-kubischen Symmetrien.
Frage der Möglichkeit einer quantitativen Korrelation von Polyederverzerrungen mit Details in den Spektren. Ableitung von Parametern der interelektronischen d-d Abstoßung in Kristallfeldern bisher nicht untersuchter Stoffgruppen (Selenite, Selenate).
