In this paper we describe the utility of an acid-catalyzed isomerization reaction, specifically, ring-contraction of methylcyclohexane to an isomeric mixture of alkylcyclopentanes as a tool for characterizing the acidic properties of a wide range of

A combination of continuous wave (CW) electron paramagnetic resonance (EPR), pulsed EPR, and pulsed electron−nuclear double resonance (ENDOR) techniques were used to obtain structural information about the Cu2+ ions in hydrated, room-temperature ev

The incorporation of Fe(III), during the synthesis, into aluminosilicate sodalite (FeSOD) and aluminophosphate sodalite, AlPO4-20 (FAPO), was investigated by continuous wave (CW) and pulsed electron paramagnetic resonance (EPR) techniques at X- and W

The incorporation of Mn(II) into framework sites in the aluminophosphate zeotype AlPO4-20, an analog of sodalite, has been investigated using pulsed electron nuclear double resonance (ENDOR) spectroscopy at 95 GHz. The field sweep echo-detected EPR s

X-band (∼9.3 GHz) pulsed ENDOR measurements were carried out on 57 Fe-substituted sodalite (FeSOD) which contains only one type of Fe(III) ( S = 5 2 ) located at a framework site. The ENDOR spectrum recorded at g = 2 shows three doublets correspond

The substitution of divalent metal ions into zeolite framework tetrahedral positions (T-sites) is well established in ALPO zeolites,1 and several zincosilicate zeolites2–4 are known, including Zn-“silicalite”(MFI).5 Reports of zinc substitution

The siting of Cu2+ in zeolites with low exchange levels has been a subject for debate due to the lack of experimental evidence that provide directly the interaction between the Cu2+ ion and the zeolite framework. High field 27Al ENDOR provided highly
