Parity violating processes are expected in muon interactions with nuclei, with possible new physics contributions dominating, but are as of yet unobserved. The use of muons captured directly into the 2S state of a high Z (\textgreater~30) material and measurement of the 2S$_{1/2}$-1S$_{1/2}$ transition photon angular asymmetry would provide a measurement of any parity violation. As a prerequisite for such a parity violation search, measurement of the photon stemming from the muon atomic radiative capture process into the 2S or 1S state, which has never before been measured, would be required as a first step. This has been conducted at the Paul Scherrer Institut using a 36 MeV/c~$\mu^{-}$ beam on a thin lead target, and the results of this measurement are presented.
