摘要：

We use broadband optical pump-probe spectroscopy to study coherent optical phonons in 1L-MoS2. We detect a strong coupling with the A'(1) mode, which is enhanced around the C-exciton peak. Ab-initio calculations of the phonon-induced band structure variation fully confirm this result. (C) 2019 The Author(s)
