The article gives an overview of the high-resolution spectroscopy of formic acid dimer (FAD) which serves as a prototype system of double hydrogen bonds. The structure as well as the dynamics of this system has been the subject of numerous experimental and theoretical studies. FAD exhibits a proton transfer tunneling in the double hydrogen bond. The proton tunneling was predicted by several theoretical groups. Using IR-high resolution it was possible to yield very precise values for the tunneling splitting. The deduced proton transfer time is in the nanosecond regime. Recent theoretical studies are in very good agreement with the experimental data obtained by high resolution spectroscopy.
