The reactions of boron with 02 and NzO hive been studied in a beam-experiment\_ Chemihmkescence is detected eniy from the B + 02 reaction for which the total chemiluminescent cross section is estimated to be 0.05 A2. Relative pop ul;ttions of vibntional levels sod cross sections for their formation

The reaction rates of atomic boron with various epovrdes have been measured m a Row tube appnratus. The btmolrcular rate constants, in umts of cm3 molecule-' s'-' ,are l,Z-zpo~ypropane (8.6 X IO-t'), 1,2~poxybutanc (8.8 x IO-"), 1,2,3,4drepo\ybutanc (5.5 X IO-"). I-chloro-2.3epouypropane (5.7 X IO
Broad chemiluminescent emission from the O('P) i-C!& reaction was observed in the 300-450 m-n region and was attributed to the B 'Z; -X %: transition of ST. First-order kinetics was observed in both reactants. The chemilumineseent rate constant, photon yield and utilization of exoergicity in chemilu
Strong infrared chemiluminescence, largely attributable to OCS, was observed in the reactions of 0 atoms with CS, in n fast flow svstem. Vibration&v excited CO was detected only weakly and at IO u
