BaCl分子在Ar+和Kr+离子激光激发下产生激光诱导荧光。单模钛：蓝宝石激光器的几条线也被用来激发近红外荧光。通过高分辨率傅里叶变换光谱法记录光谱。对以下电子跃迁进行了旋转分析：A（2）Pi --> X（2）Sigma（+），B-2 Sigma（+），--> X（2）Sigma（+），C-2 Pi --> X（2）Sigma（+），C-2 Pi--> A '（2）Delta，C-2 Pi--> A（2）Pi，C-2 Pi --> B-2 Sigma（+），E（2）Sigma（+）--> C-2 Pi，F-2 Sigma（+）--> C-2 Pi，F-2 Sigma（+）--> A（2）Pi，F-2 Sigma（+）--> B-2 Sigma（+）。进行完全拟合，同时包括这些过渡的所有测量波数。观察到的线用r.m.s. 3.9 x 10（-3）cm（-1）。在第二次分析中，A ′（2）δ、A（2）Pi和B-2 σ（+）电子态被认为在每个振动能级内形成d-复合物。导出的自旋轨道和相互作用参数导致有关的电子状态的字符的信息。(C)出版社：Academic Press，Inc.
Laser-induced fluorescence was observed in the BaCl molecule after excitation by all the Ar+ and Kr+ ion laser radiations. Several lines of a monomode titanium:sapphire laser have also been used to excite the near-infrared fluorescence. The spectra were recorded by high resolution Fourier transform spectroscopy. The following electronic transitions were rotationally analyzed: A(2) Pi --> X(2) Sigma(+), B-2 Sigma(+), --> X(2) Sigma(+), C-2 Pi --> X(2) Sigma(+), C-2 Pi --> A'(2) Delta, C-2 Pi --> A(2) Pi, C-2 Pi --> B-2 Sigma(+), E(2) Sigma(+) --> C-2 Pi, F-2 Sigma(+) --> C-2 Pi, F-2 Sigma(+) --> A(2) Pi, F-2 Sigma(+) --> B-2 Sigma(+). A complete fit was performed, including simultaneously all the measured wavenumbers for these transitions. The observed lines were reproduced with a r.m.s. of 3.9 x 10(-3) cm(-1). In a second analysis the A'(2) Delta, A(2) Pi, and B-2 Sigma(+) electronic states were considered as forming a d-complex within each vibrational level. Derived spin-orbit and interaction parameters led to information about the character of the electronic states involved. (C) 1996 Academic Press, Inc.
