（CH_3）（4）N+Br（OCF_3）（2）（-）在-70 ℃ ~-10 ℃的温度范围内分解，分解过程中放出F_2CO，得到（CH_3）（4）N+ Br F_2-。用红外光谱、拉曼光谱、19-F和13-C核磁共振谱对（CH 3）（4）N+ BrF 2-进行了表征。对于BrF_2-，在236和450 cm（-1）处观察到两个红外吸收带，在拉曼光谱中在460 cm（-1）处观察到一个吸收带，符合中心对称结构的雅阁谱。本文对BrF_2-KrF_2等电子体及其它具有D-无穷h对称性的化合物进行了从头计算。
The thermolysis of (CH3)(4)N+Br(OCF3)(2)(-) between -70 and -10 degrees C, evolving F2CO during the decomposition, gave (CH3)(4)N+BrF2-. The characterization of (CH3)(4)N+BrF2- was carried out by IR, Raman, and F-19-and C-13-NMR. For BrF2- two infrared absorption bands at 236 and 450 cm(-1) and one band in the Raman spectrum at 460 cm(-1) were observed in accord with a centrosymmetric structure. Ab initio calculations are presented for BrF2- the isoelectronic KrF2, and other related compounds with D-infinity h symmetry.
