Abstract : Emission signals at 8758 A were observed when bismuth atom vapor was introduced into a supersonic flow of electronically excited nitrogen fluoride, NF(a singlet Delta). A correlation of thermal and pressure data with the appearance of the chemiluminescence, along with a computer analysis of the IRTV observations at two wavelengths, is presented. On the basis of an analysis of these data, it is concluded that the observed emission results from the production of an excited-state bismuth atom density, Bi(doublet D three halves), on the order of 10 to the 13th power atoms cm-3 by collisional transfer with NF(a singlet Delta).
