The effect of two-body charge density due to one-pion exchange on the triton photodisintegration sum rules has been investigated. The inclusion of the two-body charge density modifies the Siegert form of the dipole operator, resulting in a change in the enhancement factor and the bremsstrahlung-weighted cross section. The expressions obtained for the integrated and the bremsstrahlung-weighted cross sections are quite general, as all the two- and three-body intermediate states have been included. The numerical work is carried out employing a variational wave function and two-body interactions having only central and tensor components. It is found that the change in the enhancement factor is quite significant (approx.16%) for the pseudoscalar coupling and only about 2% with the pseudovector coupling, and can provide information about the nuclear interaction and theories of meson exchange contributions to the triton photodisintegration sum rules.
