Solution:

$O_{2}^{- 2} - {KK}^{'} {(σ_{2 s})}^{2} {(σ_{2 s}^{*})}^{2} {({σ_{2 p}}_{z})}^{2} {(π_{2 p_{x}})}^{2} {(π_{2 p_{y}})}^{2} {(π_{2 p_{x}}^{*})}^{2} {(π_{2 p_{y}}^{*})}^{2}$

$O_{2}^{-} - {KK}^{'} {(σ_{2 s})}^{2} {(σ \overset{*}{_{2 s}})}^{2} {({σ_{2 p}}_{z})}^{2} {(π_{2 p_{y}})}^{2} {(π_{2 p_{y}})}^{2} {(π_{2 p_{x}}^{*})}^{2} {(π_{2 p_{y}}^{*})}^{1}$

$O_{2}^{} - {KK}^{'} {(σ_{2 s})}^{2} {(σ_{2 s}^{*})}^{2} {({σ_{2 p}}_{z})}^{2} {(π_{2 p_{x}})}^{2} {(π_{2 p_{y}})}^{2} {(π_{2 p_{x}}^{*})}^{1} {(π_{2 p_{y}}^{*})}^{1}$

$O_{2}^{+} - {KK}^{'} {(σ_{2 s})}^{2} {(σ_{2 s}^{*})}^{2} {(σ_{2 p_{z}})}^{2} {(π_{2 p_{x}})}^{2} {(π_{2 p_{y}})}^{2} {(π_{2 p_{x}}^{*})}^{1} {(π_{2 p_{y}}^{*})}^{0}$
