Signal intensities are given as weak (W), medium (M), or strong (S) as defined in the Supporting Information. Blank entries mean no signal was observed above the threshold intensity.

There is also weak overlapping photoproduct generated with the same chemical formula in the control photolysis of pyruvic acid.
