β¦ Synopsis
A b s t r a c t . A spectroscopic analysis of the various IR internal modes for the mixed crystal system of lithium nitrate and silver nitrate were carried out. The study aims mainly to find out the effect of partial replacement of Sgf ion by Li+ ion on the internal fundamental modes of vibrations of the NO,group in both of the ordering and disordering states of these two metallic nitrate compounds.
The characteristic variations observed are attributed to differences in polarizability from cationic sphere around the nitrate group. An interesting increase of the maximum frequency observed on passing from pure components to mixtures is attributed to ti change in force constant.
IR-spektroskopische Untersuchung des Mischkristallsystems (Li,Agl -r)NOs
I n h a l t s u b e r s i c h t . Verschiedene innere IR-Moden eines Mischkristallsystems aus Lithiumnitrat und Silbernitrat warden spektroskopisch untersucht. Ziel der Untersuchungen ist die Klarung des Einflusses der partiellen Substitution von Ag+ durch Li+ auf die Grundschwingungen der NO,--Gruppe sowohl im geordneten als auch ungeordneten Zustand dieser beiden Metallnitratverbindungen. Die beobachteten charakteristischen Verschiebungen werden dem Unterschied in der Polarisierbarkeit der kationischen Schale um die Kitratgruppe zugeschrieben. Ein interessanter Anstieg der beobachteten maximalen Frequenz beim Ubergang von den reinen Komponenten zur Mischung wird mit einer Anderung in den Kraftkonstanten erklart.
