Fluorescence of nitric oxide excited by the 184.9 nm mercury resonance line

Abstract

The fluorescence of NO was obtained by excitation from the 184.9 nm resonance line of a low pressure mercury lamp. It was found that the β (v′=9) emission was induced by the absorption of the 184.9 nm line for [NO]=1.0 torr. Quenching of the β (v′=9) bands by He or N2 molecules was accompanied by an enhancement of the γ bands, v′=4 or 0 and 1, respectively. When CO was added to NO, intensities of the emission were weakened. These effects were explained by the following reaction scheme.

Intercalation kinetics of the sodium(1+) ion into titanium disulfide using the pressure-jump technique

“…The grown crystals were shown by X-ray diffraction to have the 1T-Cdl2 type structure with lattice parameters of a = 3.406 Á and c = 5.703 Á. This c value corresponds to the nonstoichiometric Ti105S2 according to Thompson et al,2 indicating the presence of a small amount of interstitial Ti atoms. Powders of TiS2 were hydrolyzed in NaOH solution with pH >10 to form NaxTi2_xOx (0 < x < 1).…”
