摘　　要：在流动余辉装置上,对高纯氮气空心阴极放电产生了活性氮,首次利用产生的活性氮与CHBr3分子碰撞传能产生了亚稳态的NBr(b1Σ+)自由基,并在放电管的下游观察到了NBr(b→X)跃迁发射谱,利用实验室已有的计算机程序计算了NBr(b→X)发射谱中各振动跃迁的Franck-Condon因子,并对该发射谱进行了理论模拟.由此分析出,观察到的NBr(b→X)发射谱满足振动温度为8 000 K的玻尔兹曼分布.The chemiluminescence of active nitrogen reaction with CHBrs has been investigated in a flowing afterglow reactor. Strong emission spectrum has been observed in the wavelength range from 550 to 750 nm, which is ascribed to NBr（b→X） transition. The Franck-Condon factor of vibrational transition is calculated with our computer program,and the emission spectrum of NBr（b→X） transition is simulated. It shows that the vibrational distribution satisfied the Boltzmann distribution of T= 8000 K.
