TOXIKOLOGISK Formaldehyd (H2CO) innehåller plana molekyler. En molekyls form beror på de atomer som gör det och de elektroner som tillhör den centrala atomen. Formaldehyd (H2CO).

The absolute vacuum ultraviolet (VUV) photoionization spectra of the hydroperoxyl radical (HO2), hydrogen peroxide (H2O2), and formaldehyde (H2CO) have been measured from their first ionization thresholds to 12.008 eV. HO2, H2O2, and H2CO were generated from the oxidation of methanol initiated by pulsed-laser-photolysis of Cl2 in a low-pressure slow flow reactor. Reactants, intermediates, and
