trans-(Ru(NH{sub 3}){sub 4}P(OEt){sub 3}H{sub 2}O){sup 2+}, trans-(Ru(NH{sub 3}){sub 4}(P(OEt){sub 3}){sub 2}){sup 2+}, and trans-(Ru(NH{sub 3}){sub 4}P(OEt){sub 3}CO){sup 2+} were photolyzed with light of 313 nm on the lowest energy ligand field excited state. Photoaquation of the thermally substitution inert ammonia is observed for all three complexes with {phi} {congruent} 0.030 mol/einstein. trans-(Ru(NH{sub 3}){sub 4}(P(OEt){sub 3}){sub 2}){sup 2+} undergoes P(OEt){sub 3} photoaquation with {phi} {congruent} 0.12 mol/einstein, while trans-(Ru(NH{sub 3}){sub 4}P(OEt){sub 3}CO){sup 2+} displays CO photoaquation with {phi} = 0.07 mol/einstein. The results suggest that the electronic configuration of the lowest energy excited state of these complexes have contributions from E and A{sub 2} states. Furthermore, in trans-(Ru(NH{sub 3}){sub 4}P(OEt){sub 3}CO){sup 2+} the photoaquation of CO is explained by depopulation of a bonding d{pi} orbital and population of a {sigma}* orbital.
