用超声膨胀束与激光束交叉产生的激发光谱和荧光光谱观察了汞的三原子货车德瓦耳斯配合物。由汞和（惰性）载气（RG）组成的膨胀束在三个单独的光谱区域中被激发：在Hg 2537 A组合线附近，（禁戒）Hg 6（3）P2 <-- 6（1）S 0原子跃迁（2200-2290），Hg 2G 0（+）u <--X 0（+）g跃迁区（1975-2080）。在光谱范围1900-6000 A内记录的所得光谱，除了已知的Hg、Hg 2和HgRG组分之外，还包含归因于Hg 2 RG和Hg 3络合物的新吸收和荧光带。版权所有1998学术出版社。版权所有1998学术出版社
Triatomic van der Waals complexes of mercury have been observed in a supersonic expansion beam crossed with a laser beam to produce excitation and fluorescence spectra. The expansion beam consisting of mercury and a (noble) carrier gas (RG) was excited in three separate spectral regions: in the vicinity of the Hg 2537 A intercombination line, near the (forbidden) Hg 6(3)P2 <-- 6(1)S0 atomic transition (2200-2290 A), and in the region of the Hg2 G0(+)u <-- X0(+)g transition (1975-2080 A). The resulting spectra, which were recorded in the spectral range 1900-6000 A, contained, in addition to the known Hg, Hg2, and HgRG components, new absorption and fluorescence bands that are ascribed to Hg2RG and Hg3 complexes.
