In the electronic spectra of $\left[\mathrm{CrF}_{6}\right]^{3-}$, absorption bands observed at 670,440 and 290 nm are, respectively, due to the transitions.
(a)${}^{4}\mathrm{A}_{2\mathrm{g}} \rightarrow {}^{4}\mathrm{T}_{1\mathrm{g}}(\mathrm{P})$, ${}^{4}\mathrm{A}_{2\mathrm{g}} \rightarrow {}^{4}\mathrm{T}_{1\mathrm{g}}(\mathrm{F})$ and ${}^{4}\mathrm{A}_{2\mathrm{g}} \rightarrow {}^{4}\mathrm{T}_{2\mathrm{g}}$
(b)${}^{4}\mathrm{A}_{2\mathrm{g}} \rightarrow {}^{4}\mathrm{T}_{1\mathrm{g}}(\mathrm{P})$, ${}^{4}\mathrm{A}_{2\mathrm{g}} \rightarrow {}^{4}\mathrm{T}_{2\mathrm{g}}$ and ${}^{4}\mathrm{A}_{2\mathrm{g}} \rightarrow {}^{4}\mathrm{T}_{2\mathrm{g}}(\mathrm{F})$
(c)${}^{4}\mathrm{A}_{2\mathrm{g}} \rightarrow {}^{4}\mathrm{T}_{1\mathrm{g}}(\mathrm{F})$, ${}^{4}\mathrm{A}_{2\mathrm{g}} \rightarrow {}^{4}\mathrm{T}_{1\mathrm{g}}(\mathrm{P})$ and ${}^{4}\mathrm{A}_{2\mathrm{g}} \rightarrow {}^{4}\mathrm{T}_{2\mathrm{g}}$
