Protolytic equlibria of bromazepam / Protolitičke ravnoteže bromazepama
(Srpsko hemijsko društvo, Beograd, 2002)
The protolytic equilibria of bromazepam, an ampholyte sparingly soluble in water, in homogeneous and heterogeneous systems were studied in the pH range 0–14 at 25ºC and at ionic strength of 0.1 mol/dm3 (NaCl). On the basis ...
Structural modifications of Cu(II) 12-tungstophosphoric acid salt studied by IR and Raman spectroscopy / IR i ramanska ispitivanja strukturnih modifikacija bakarne soli 12-volframfosforne kiseline
(Srpsko hemijsko društvo, Beograd, 2000)
In this paper local processes and structural phase transformations of the copper salt of 12-tungstophosphoric acid are investigated. The structural phase transformations were followed through bands, characteristic for the ...
