CN（B^2Σ~＋）激发态光谱的研究

Spectroscopy of Excited CN (B￣2Σ+ ) Fragment

研究亚稳态原子Ｈｅ（２３Ｓ）与ＣＨ３ＣＮ的能量转移反应，获得了ＣＮ（Ｂ２Σ＋－Ｘ２Σ＋）的近紫外辐射光谱。根据光谱强度，研究了ＣＮ（Ｂ２Σ＋）的形成速率和振动布居，并探讨了传能反应机理。

The energy transfer reaction of metastable He (23S) with CH3CN has beeninvestigated. Near-violet emission spectra of CN (B - X ) and CH (A - X ) wereobserved. Based uPOn the spectra of excited fragment we estimated the formation rateconstant and vibrational POpulation of CN (B ). The reaction mechanism were alsodiscussed.
