- 中文摘要：
氣態的氯化溴的共振拉曼現象已觀察到，在5145A雷射光激發下，此現象很微弱。雖然在4579A光激發時，可增強
但與鹵素氣體，氯、溴、和碘比較仍是很弱。又在拉曼光譜中發現有熱帶的加強，此加強現象又與雷射光的頻率及功率有
關。一個因與在3TTou+能階的溴分子或在2P1/2能階的溴原子碰撞激發氯化溴的機構可說明此拉曼光譜的熱帶因碰撞而
加強的現象。
- 英文摘要：
The resonance Raman phenomenon of gaseous bromine chloride was observed with excitation byvarious argon ion laser lines. It was weak in 5145 A excitation and became stronger in 4579 A excitation.However it was still much weaker compared with the halogen gases, Cl2, Br2 and I2. The enhancementfrom the hot bands was found in the Raman spectra. It depended on the laser frequency as well as thelaser power. A mechanism of collisional excitation of BrCl by Br2 molecules in 3πou+ state or Br atomsin2 pl/2 state was proposed for this collision enhanced Raman scattering phenomenon.
