本工作用红外双共振技术测量了BCl3分子的振动激发态吸收光谱。观察了分子间的多种弛豫过程及能量转移过程。得到关系式PτV-V(11BCl3)=3微秒·托。观察到径向声波对双共振信号的调制,声速为2×104厘米/秒,与计算值相符。The absorption spectrum of the vibrational excited state in BC13 has been obtained by means of a infrared double resonance technique. A variety of relaxation processes and energy transfer processes were observed. The relationship PτV-V(11BCl3)= 3μs·torr has been obtained. A radial sound modulation was observed on the double resonance signal. The sound velocity is 2×104cm/sec and it agrees with the calculated value.
