Parametric Study of NCl(alpha sup 1 delta), NCl(beta sup 1 Sigma) from the Reaction of Cl/Cl2/He + HN3/He
Abstract
By means of Microwave generator chlorine diluted by helium is dissociated to chlorine atoms that subsequently react with hydrogen azide to produce excited states of NCl(alpha sup 1 delta) and NCl(beta sup 1 Sigma). In this paper, the intensity of NCl(alpha sup 1 delta) and NCl(beta sup 1 Sigma) emission dependent on the flow rates of different gases is studied. Moreover, the production of NCl(alpha sup 1 delta) and NCl(beta sup 1 Sigma) along the reaction tube is also investigated. By using a simple titration method, we obtain the dissociation efficiency of molecular chlorine up to 100% at the flow rates of chlorine no more than 1-mmol/s. We also achieve the quenching rate of NCl(alpha sup 1 delta) by Cl2 is about 4 x 10(exp -13) cu cm/sec-molec with excess flow rates of chlorine. Finally, the optimum parameters for NCl(alpha sup 1 delta) and NCl(beta sup 1 Sigma) production are summarized.
