For overall photosynthetic response, take a look at the YPF (yield photon flux). See, for example:
That normalized spectra details the known response of the photosynthesis systems and the relative quantum efficiency of conversion. If anything, it’ll give you an idea of the breadth of the spectrum and how efficient the plant utilizes that spectra. You’ll note that it does extend into the UV regions. It will not provide necessarily any more information that might be useful beyond that. Such as the differentiation between the PSI/II systems or the effects of heavy UV, etc…
