UV/visible spectrophotometric studies of the interactions of thiomolybdates, copper(II) and other ligands
1Department of Chemistry, 110 Science Place, University of Saskatchewan, Saskatoon, Saskatchewan, S7N 5C9 Canada.
Abstract:
Thiomolybdates (TMs) formed in the rumen are known to be involved in copper deficiency in ruminants. However, which particular TMs are formed has been an issue of contention. In this study, we have measured the relative proportions of the different TMs, formed under conditions simulating those within the rumen fluid of ruminants prone to copper deficiency, using UV/visible spectroscopy. Pure synthesized TMs have also been used to study spectrophotometrically the interactions between the TMs and copper(II) in the presence and absence of some inorganic ligands, low molecular mass complexing agents and bovine serum albumin in aqueous solutions.

Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human eye.
