【Abstract】 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(11BCI3) = 3μs ·torr has been obtained. A radial sound modulation was observed on the double resonance signal. The sound velocity is 2 × 104 cm/sec and it agrees with the calculated value.更多还原
