The large direct band gap in a monolayer of MoS2 leads to the appearance of the interband dipolar mode which couples to the intraband plasmon. This result is useful for our understanding of the collective excitations in MoS2. The renormalized dipolar mode is close to its bare value, while coupling suppresses the plasmon mode.
