Proton transfer in [(HCOOH).sub.2]: An IR high-resolution spectroscopic study of the antisymmetric C-O stretch

The fully analyzed high-resolution spectrum of the carboxylic acid dimer [(HCOOH).sub.2] in the gas phase is described. The antisymmetric C-O stretch vibration were recorded by high resolution IR spectra and the proton transfer time of 1.0 and 1.7 ns for the ground and the vibrationally excited state, respectively was determined.
