Paper 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(a1(Delta) ) and NCl(b1(Sigma) ). In this paper, the intensity of NCl(a1(Delta) ) and NCl(b1(Sigma) ) emission dependent on the flow rates of different gases is studied. Moreover, the production of NCl(a1(Delta) ) and NCl(b1(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 percent at the flow rates of chlorine no more than 1 mmol/s. We also achieve the quenching rate of NCl(a1(Delta) ) by Cl2 is about 4 X 10-13 cm3/sec molec with excess flow rates of chlorine. Finally, the optimum parameters for NCl(a1(Delta) ) and NCl(b1(Sigma) ) production are summarized.
