In 2009 fulminic acid, HCNO, was first detected in space in the three starless cores B1, L1544 and L183.[1] The isomer isocyanic acid, HNCO, is also ubiquitous in interstellar systems.[2] Due to their composition of Hydrogen, Carbon, Nitrogen and Oxygen these molecules have been proposed to have a prebiotic role as intermediates for organic life. Investigating the interaction of these molecules with X-ray radiation is critical in understanding their fate in space.
As such, we present the gas phase auger electron spectra of fulminic acid which were recorded at the PLEIADES beamline at the Synchrotron SOLEIL in France. Fulminic acid was synthesized by preparative pyrolysis.[3] The spectra are compared to theoretical simulations and previously recorded spectra of isocyanic acid.
