| Popis: | Forty-nine bands arising fromhave been detected in the emission spectrum offrom two sources: (i) the reaction of Br or Br2with ClO2, in whichis populated in the transfer reaction,3and (ii) the radiative combination of bromine and chlorine atoms,5The populations of the higher levels offormed in reaction (3) are less than in reaction (5). In reaction (3),is evidently formed via a triangular transition state similar to that postulated previously; the rate constant,k3, was found to beThe combination of ground state iodine, and chlorineatoms was also found to be chemiluminescent in the red and near infrared region, and fifty-seven bands of the system, with, have been recorded. The radiative combination of ground-state chlorine atoms has been reinvestigated, and transitions offromv' ≼ 14 have been detected. Combining band head analyses of these emission spectra with previous data, the following constants (in cm-1) are reported:The reasons for the predominant radiation, during atom combination processes, fromtype states for Cl2and BrCl, and from the3II1state for ICl, are discussed in relation to Brown & Gibson’s (1932) finding of a maximum in the potential energy curve ofleading toandas dissociation products. |
