Sažetak
In this work we present the study of temperature influence on the other band in the UV spectrum of NO_3^-(aq)centred at 200 nm. We also studied temperature effect on the d-d transitions of Ni^+2(aq) at different concentrations in the temperature range of (10...70)°C. Significant influence of temperature on the position and intensity of the corresponding spectral bands, accompanied with the occurence of well-defined isosbestic points, was observed. Analogously to the case of nitrate ion, these spectral changes could be explained by temperature dependent breaking/formation of hydrogen bonds in the cation hydration shell.
