摘要
The rotationally resolved origin band in the 2 E-2(')<--X (2)A(1)(') electronic spectrum of cyclic B-3 has been observed by cavity ring down spectroscopy in the gas phase. The B-3 molecule was generated in a supersonic planar plasma containing decaborane (B10H14) and neon as a carrier gas. The rotational structure pattern is that of a cyclic molecule. It is analyzed assuming an equilateral triangle in both electronic states. The band origin is determined to be 21 853.52 cm(-1), and the bond lengths 1.603 77(106) Angstrom in the ground and 1.619 07(96) Angstrom in the excited electronic state are inferred from analysis of the rotational structure.
