Low energy electron attachment to condensed formic acid [PDF]

open access: yes, 2008
Dissociative electron attachment to formic acid in the condensed phase is studied using improved mass spectrometric detection of the negative ion fragments. The desorbed yields are measured as a function of incident electron energy in the range between 3

The genealogical tree of ethanol: gas-phase formation of glycolaldehyde, acetic acid and formic acid [PDF]

open access: yes, 2017
Despite the harsh conditions of the interstellar medium, chemistry thrives in it, especially in star forming regions where several interstellar complex organic molecules (iCOMs) have been detected. Yet, how these species are synthesised is a mystery. The

Submillimeter Spectrum of Formic Acid

open access: yes, 2008
We have measured new submillimeter-wave data around 600 GHz and around 1.1 THz for the 13C isotopologue of formic acid and for the two deuterium isotopomers; in each case for both the trans and cis rotamer.
