Laser-Induced Fluorescence Studies of Excited Sr Reactions. † 1. Sr(3P1) + HF
Electronic ground-state SrF (X2Σ) products formed in the reaction of electronically excited Sr(3P1) with HF are studied using laser-induced fluorescence (LIF) detection. Sr atoms are excited to the 3P1 state using a frequency-narrowed and -stabilized linear titanium−sapphire laser at 689.3 nm. The v...

| Zusammenfassung: | Electronic ground-state SrF (X2Σ) products formed in the reaction of electronically excited Sr(3P1) with HF are studied using laser-induced fluorescence (LIF) detection. Sr atoms are excited to the 3P1 state using a frequency-narrowed and -stabilized linear titanium−sapphire laser at 689.3 nm. The vibrational and rotational population distributions in the SrF(X2Σ) products are deduced from the LIF spectra of the B2Σ−X2Σ and A2Π3/2−X2Σ transitions using spectrum simulation. The results show a strong dependence of the SrF internal energy distribution on the impact parameter. The light H atom is ejected with high translational energy. |
