2. Cobalt spinels can be found on Baffin Island in Nunavut. The blue color of these gems comes from cobalt (II) in a tetrahedral site. A spectrum of a Baffin Island spinel (and an image of the gem itself if given at right. Note: each tick on the x-axis is 100nm in the spectrum. (a) assign the first two transitions for Co (II) in a spinel ( 2 marks). (b) Use the appropriate Tanabe SuganoDiagram to calculate Dq and B for each of those gemstones. Be sure to show your work so we can understand what you did. (2 marks for procedure +2 marks for correct values of Dq and B) 2. Cobalt spinels can be found on Baffin Island in Nunavut.
