Mass spectrometric investigation of neutral and charged constituents in saturated vapor over PrI3

Study of Molecular and Ionic Vapor Composition over CeI3by Knudsen Effusion Mass Spectrometry

“…The present work continues our systematic investigations of the molecular and ionic sublimation of lanthanide halides by KEMS; see for example, [10][11][12][13][14]. The composition of the saturated vapor of CeI 3 was determined and the thermochemical data of the vapor constituents were refined on the basis of the latest sets of molecular parameters.…”

“…The standard formation enthalpies, Δ f −860 ± 23 kJ⋅mol −1 was used as reference value. It was obtained by recalculation of the data (−865 ± 25 kJ⋅mol −1 )[13] with the thermodynamic function used in this work. The experimental equilibrium constants of reaction(3) and reaction (4) investigated over pure CeI 3 are listed in…”
