We report the identification of heavy Rydberg resonances in the ion-pair spectra of I2, Cl2, ICl, and IBr. Extensive vibrational progressions are analysed in terms of the energy dependence of the quantum defect δ(Eb) rather than as Dunham expansions. This is shown to define the heavy Rydberg region, providing a more revealing fit to the data with fewer coefficients and leads just as easily to n...

A method is described for the determination of bromides in biological samples using neutron activation analysis. The specificity of this method eliminates sources of interference from other halogens and contamination of analytical agents with extraneous bromide. In duplicate samples of blood, at varying concentrations of potassium bromide, the mean difference was 4.5% ±1.95 and the mean of the ...

Aryldiazo substituents were used in nucleophilic aromatic substitution reactions of halogens. The Ph-N=N- group activates ortho fluorine atoms toward alkylthiolation under mild conditions. In contrast, the Me(2)N-C(6)H(4)-N=N- group has virtually no activation effect in nucleophilic aromatic substitution, and serves as a "neutral" mask for the amino group. The Ph-N=N- group was efficiently intr...
