We report a search for the decay {psi}(2S){yields}{gamma}{eta}{sub c}(2S) in a sample of 25.9x10{sup 6} {psi}(2S) events collected with the CLEO-c detector. No signals are observed in any of the 11 exclusive {eta}{sub c}(2S) decay modes studied, or in their sum. Product branching fraction upper limits are determined as a function of {Gamma}[{eta}{sub c}(2S)] for the 11 individual modes.
