Which statement is true regarding the electronic spectrum of the carbonyl fragment, {C=O}, which may undergo either or both a n T* and t -→ IT transitions in the molecule pictured below? The n → T* absorption is at a shorter wavelength than the t → T* absorption. The n T* absorption is at a longer wavelength than the a → T* absorption. The n → IT* absorption is at a similar wavelength to the n → T* absorption. The n-→ T* absorption is variable depending on the wavelength absorbed. An n → T* absorption is not allowed by selection rules.
