This 1FLO asks students to interpret an electronic spectrum of 5 NiX42- anions. Students will determine the relative ligand field strength, (re)familiarize themselves with terms such as "redshift" and "blueshift", and consider possible metal complex geometries.
Students (re)familiarize themselves with relationship between wavelength (λ) and wavenumber (cm-1).
Students recall 4-coordinate geometries.
Students define the terms “redshift” and “blueshift.”
Students analyze data to construct a partial spectrochemical series.
This activity could be used as either a guided introduction to the spectrochemical series, or as an in-class activity to review after introduction. If used as an introduction, question 4 may need modification.
