| 英文摘要 | The previously unknown arsenic carbide (AsC) free radical has been identified in the gas phase through a combination of laser-induced fluorescence (LIF), single vibronic level emission, and stimulated emission pumping (SEP) spectroscopy in a supersonic expansion. The As(12)C and As(13)C isotopologues have been detected as products of an electric discharge in mixtures of arsine (AsH(3)) and carbon dioxide ((12)CO(2) or (13)CO(2)) in high pressure argon. The B(-2)Sigma(+)-X(-2)Sigma(+) band system was recorded by LIF spectroscopy and emission transitions from the B state down to the ground state and to the low-lying A(-2)Pi(i) state were observed. High resolution studies of the B-X 0-0 band by LIF and the B-A 0-0 band by SEP spectroscopy enabled a determination of the molecular structures in the three states. Although CN, CP, and AsC have similar X(-2)Sigma(+) and A(-2)Pi(i). states, the B(-2)Sigma(+) state molecular orbital configuration of CP and AsC differs from that of the CN free radical.
