title: Proton tunneling estimates for malonaldehyde vibrations from supersonic jet and matrix quenching experiments.
abstract: FTIR tunneling splittings for a range of fundamental excitations of malonaldehyde are determined from adiabatic cooling and symmetry breaking experiments in three different molecular states (isolated, coated by Ar layers and embedded in bulk Ar matrices), showing that there is room for improvement in available theoretical models.
