摘要：

In their Comment concerning the spin-(1)(2) resonance in MEH-PPV, Yang [Phys. Rev. B 75, 246201 (2007)] measure the microwave frequency response twice: once in the time domain and once in the frequency domain. Even accounting for possible variation in experimental conditions and the possible nonlinear dependence on microwave power, the reported data are inconsistent. We also demonstrate that the phase, microwave power, and temperature dependent data do not contradict the triplet-polaron quenching model. We conclude that the criticism in the Comment is unfounded.
