Question

How to determine which complex absorbs light of longer wavelength?

Answer 1

$\huge\underline{Answer:}$

A solution that looks yellow absorbs light that is violet, which is roughly 410 nm from the color wheel. Since it absorbs high energy, the electrons must be raised to a higher level, and Δo is high, so the complex is likely to be low spin. Example 2: An octahedral metal complex absorbs light with wavelength 535 nm.
