The analytic energy gradient of power pertaining to atomic coordinates comes from for the fragment molecular orbital (FMO) strategy coupled with time-dependent thickness useful principle (TDDFT). The response terms arising from the employment of a polarizable embedding tend to be derived. The obtained analytic FMO-TDDFT gradient is shown to be accurate compared to both numerical FMO-TDDFT and unfragmented TDDFT gradients, during the level of two- and three-body expansions. The g
