We discuss the available data for the differential and the total cross section for the photodisintegration of ${}^3\mathrm{He}$ and ${}^3\mathrm{H}$ and the corresponding inverse reactions below $E_{\gamma }=100\mathrm{}$ MeV by comparing with our calculations using realistic $\mathrm{NN}$ interactions. The theoretical results agree within the error bars with the data for the total cross sections. Excellent agreement is achieved for the angular distribution in the case of ${}^3\mathrm{He},$ whereas for ${}^3\mathrm{H}$ a discrepancy between theory and experiment is found.
