Product Details of 61-82-5. The Name is 1H-1,2,4-Triazol-5-amine. Through research, I have a further understanding and discovery of 61-82-5.
Four C2H4N4 structural isomers are investigated with fs laser-induced breakdown spectroscopy. Plasma emissions, C I, H-alpha, the CN violet system (B-2 sigma(+)-X-2 sigma(+), Delta nu = 0 sequence) and C-2 swan system (d(3)pi(g)-a(3)pi(u), Delta nu = 0 sequence) are measured. The temporal evolution of the characteristic emission intensity is obtained for each emission and their lifetimes are calculated. The lifetimes of the molecular emissions are much longer than those of the atomic emissions. Characteristic emission intensities and lifetime are correlated with the molecular structures of the four isomers to a certain extent. Plasma temperature is extracted by fitting the spectrum of the CN violet system, B-2 sigma(+)-X-2 sigma(+); Delta nu = 0 sequence, and is weakly correlated with the molecular structures of the four isomers. Using the characteristic emission intensities as input, principal component analysis (PCA) and artificial neural network (ANN) analysis are performed and the individual isomers can be well identified with PCA or ANN.
