摘要: Laser ablation molecular isotopic spectrometry (LAMIS) recently was reported for rapid analysis by measuring emission from laser-induced plasmas at atmospheric pressure. This research utilized the LAMIS approach to study C2 formation laser of carbon samples in a neon gas environment 0.1 MPa. The shift Swan system Δν = 1 band chosen isotope analysis. Temporal and spatial resolved measurements 12C2, 12C13C, 13C2 show that forms recombination reactions plasma. A theoretical simulation used determine temperature bands extract ratio 12C/13C derived 13C2. Our data varies with time after pulse distance above sample. deviates nominal (2:1) early times closest sample surface. These provide understanding chemical p...
