Microwave spectrum of the rubidium monoxide RbO radical
Using a microwave spectrometer, the rotational spectra of 85RbO and 87RbO were recorded. Spectral lines which were supposed to be caused by RbO started to appear when the temperature of the cell reached 350°C and became strong at 500 to 550°C. All the observed spectra were analyzed by a least-squares method. Overall, the molecular parameters derived from the spectra provide invaluable information on the rubidium monoxide radical.
Study of the chemiluminescent reaction between alkali dimers and oxygen atoms
The reaction of alkali dimers with oxygen atoms has been studied in a crossed beam experiment.Strong chemiluminescence of the reaction products was observed.It is shown that the luminescence was emitted by alkali from the reaction M2+O->MO+M* (M alkali atom).M* can be excited up to exoergicity of this reaction at least in the cases M=Cs and Na.For M=Cs, detailed rate constants for the excitation of the different excited states have been determined using both laser induced fluorescence and chemiluminescence.The rates decrease nearly exponentially as a function of the excitation energy.They partly follow the expectation of statistical theories.Absolute reaction cross sections have been determined for all of the reactions investigated.They agree partially with those predicted by the harpoon model.
