We propose a method to investigate the vibrational dynamics of a single polyatomic molecular ion that is co-trapped with an atomic ion. Quantum logic techniques will be used to detect the recoil of a single photon absorption event in the molecule on the atomic ion. This single-molecule recoil spectroscopy can be extended to a pump-probe scheme to investigate ultrafast molecular dynamics. In particular, intra-molecular vibrational dynamics of a single molecular ions can be tracked. We analyze the experimental requirements to investigate the vibrational dynamics in the Cyanoacetylene cation C3HN+
