Abstract:The rotational spectra of three deuterated isotopologues of the dimer of formic acid have been measured, thank to the small dipole moment induced by asymmetric H --textgreater D substitution(s). For the HCOOH-DCOOH species the concerted double proton transfer of the two hydroxyl hydrogens takes place between two equivalent minima and generates a tunneling splitting of 331.2(6) MHz. From this splitting a barrier to proton tunneling of about 30 kJ/mol has been estimated._x000d_
