Beschreibung:
The vibrational spectroscopy of formic acid and its dimer (including deuterated isotopologues) is investigated using Raman and FTIR jet spectroscopy. The vibrational spectroscopic record of monomeric formic acid is reviewed, corrected, and extended. The monomer database has been digitised and can be found online (https://qmbench.net). The intramolecular vibrational fingerprint spectra of formic acid dimer (FAD) are revisited, bridging the gap between the completed intermolecular van der Waals and intramolecular carbonyl stretching region, providing a plethora of environment-free combination...
