Abstract:

Tin vapor has been reacted with N2O, NO2, O2, and F2 to produce SnO and SnF in a flame. Reactions of Sn with O2 and NO2 produced very weak chemiluminescence, whereas Sn Br2 and Cl2 produced no detectable light emission. The highest photon yield measured was 6.7 for SnO emission that resulted from the reaction of Sn N2O in Ar at a Sn concentration of 3 X 10 to the 13th power, The maximum SnF yield measured was 0.3 for Sn F2. The spectral character of the SnO chemiluminescence generated in the Sn N2 O reaction was found to be a strong function of pressure 0.5 to 25 Torr and carrier gas identity Ar, He, N2 in the flow-tube reaction system.
