【Abstract】 The free radical of CICOCO has been investigated theoretically and experimentallyGeometry、vibrational frequencies and dissociative energy barrier of the ground state of CICOCOwere obtained by ab initio calculations. By 351 nm photolysis of (CICO)2, CICOCO’s infraredendssion at 1844 cm-1 was recorded by TRFTIR spectrometer.更多还原
