IR-spectroscopic manifestation of the diacetyl radical anion produced by irradiation of diacetyl in a dimethyl ether matrix at 7K

The strongest vibrational feature of a radical anion produced from the diacetyl molecule under radiolysis in a low-temperature dimethyl ether matrix has been characterized for the first time by the analysis of IR- and EPR-spectroscopic data supported by quantum- chemical calculations.
