  "abstract": "Chirality-induced spin selectivity (CISS) is usually associated with molecular handedness. The possible contribution of chiral phonons is less established. We study a helical tight-binding model in which local phonon angular momentum modulates spin-dependent nearest-neighbor hopping. Fewest-switches surface hopping calculations give the transmitted spin polarization $\\mathrm{SP}=aC+b\\mathrm{PH}$. Here $C$ is the molecular chirality and $\\mathrm{PH}$ is the phonon chirality. A mirror symmetry reverses $C$, $\\mathrm{PH}$, and $\\mathrm{SP}$ simultaneously. This symmetry excludes both a chirality-independent offset and a $C\\cdot\\mathrm{PH}$ term. The phonon contribution can therefore enhance, cancel, or reverse the molecular CISS signal.",
