Synthesizing and Investigating Cobalt Complexes: UV-Vis and Structure-Property Relationships

Post-Lab Activity


26. Below are two different spectrochemical series that can be derived from the literature. How do your experimental spectrochemical series compare?


Cyanide > Nitrite > Phenanthroline > Ethylenediamine > Ammonia > Glycine > Water > Oxalate > Carbonate
