How do you use uv spectroscopy to determine to the oxidation state of transition metals?

In some simple cases, when transition metals are in solution in water without a complex matrix, the UV spectra of different oxidation states of transition metals are different: Fe2+ and FE3+ Cr3+/Cr6+...complexes can be formed with organic molecules with different spectra for different oxidation states, and FIA (Flow Injection Analysis) can be used. In difficult cases (complex mixtures) multivariate models can be used successfully (PLS), but elaborating calibration models can be tedious!

How is UV spectroscopy generally used?
Its used to separate and or transition chemicals from one state to another, identify chemicals, verify chemical naturals, transition different metals ions, metal atoms, and other high intense chemicals.
Are transition metals better conductors than alkali metals?
transition metals
Do transitionn metals have a consistent oxidation number?
transition metals have variable oxidation states
What are applications of visible spectroscopy?
analysis of the transition metals and highly conjugated organic compounds
What is the difference between late transition metals and early transition metals?
The early vs. late transition metals differ in their oxidation states (each metal has different possible oxidation states). Electrons have a stronger attraction to the protons in the late transition metals, so the later transition metals form bonds that are harder to break. You can read more about transition metal properties from the links below.Source(s):

Which family has elements that have more than one oxidation number?

Why do transition metals have multiple oxidation states?
Transition metals have multiple oxidation states due to the number of electrons that an atom loses, gains, or uses when joining another atom in compounds. It also determined the ability of an atom to reduce.
How are oxidation states if transition metals indicated in the names of metal compounds?
Roman numerals are used to indicate oxidation states. Apex
Which d block elements are not classified as transition elements?
Sc and Zn are not classified as transition metals. They does not have stable different oxidation numbers.
Why do transition metals have variable oxidation states?
Transition metals can move electrons between the outer shell and the d d orbital. For example, copper can either lose its 2 s electrons or move one of those s electrons into d orbital, which is one electron short of being full.
Which group has more than one positive oxidation state?
The transition metals (groups 3-12) can have more than one positive oxidation state. When you write the names of compounds with transition metals, you note their oxidation state with roman numerals, e.g. iron (II) oxide and iron (III) oxide.
