The structural phase transition from the tetragonal to the orthorhombic phase of doped and undoped samples of La2-xSrxCuO4 has been investigated by using inelastic neutron scattering techniques. The rotational nature of the soft mode leads to moderate electron-phonon coupling and the mode is unlikely to enhance significantly conventional phonon mediated superconductivity.
