Abstract

By means of a microwave generator chlorine diluted by helium was dissociated to chlorine atoms that subsequently reacted with hydrogen azide to produce the excited states of NCl(a¹Δ). Meanwhile, molecular iodine with carrier gas of helium reacted with atomic chloride to produce atomic iodine which then was pumped to excited state of I(²P_1/2) by an energy transfer reaction from NCl(a¹Δ). In this paper, the changes of NCl(a¹Δ) and NCl(b¹Σ) emission intensity is presented upon admitting I₂/He into the stream of Cl/Cl₂/He/HN₃/NCl(a¹Δ)/NCl(b¹Σ). Moreover, the production of excited state of atomic iodine I(²P_1/2) dependent on flow rates of gases was also investigated. The optimum parameters for I(²P_1/2) production are given.
