In this series of complexes the π → π ∗ transition energy increases with increasing number of d ξ-electrons and this is attributed to metal-ligand by: INTRODUCTION THE HIGH-TEMP~.RATUm~ absorption spectra of the 3dn transition metal ions dissolved in molten alkali metal halides have been extensively investigated over the past 15 years[I-3] but there have been relatively few studies of the spectra of ions of the 4dn and 5d" transition metal ions.
The present paper is concerned with Pt(II).Cited by: 3. Electronic spectroscopy in multi d electron ions • in order to understand the spectroscopy of d ions with more than one d electron we must take the effect of e-- e-repulsion into account (we have ignored this so far) • each e-has spin and orbital angular but it is the interaction of the TOTAL RESULTANT spin and angular momentum with light that is importantFile Size: KB.

The laboratory is operationally very simple and has students record the UV-vis spectra of transition metal sulfate salts in water using volumetric technique. They record the molar absorptivities for each peak and use this data to determine the number of waters of hydration for each salt by comparing with literature absorptivity values.

The absorption spectra of solutions of alkali halides and of halogen gases in alkali halide eutectic melts are described. The spectra of the halides are interpreted as charge transfers from the anion. The halogens are shown to dissolve in these solvents to form trihalide by: A metal ion in aqueous solution or aqua ion is a cation, dissolved in water, of chemical formula [M(H 2 O) n] z+.The solvation number, n, determined by a variety of experimental methods is 4 for Li + and Be 2+ and 6 for elements in periods 3 and 4 of the periodic table.
