    To secure a high degree of precision in the measurement of excitation temperatures from relative intensities of spectral lines, the choices of the lines and the best Ag-values deserveto be discussed.Twenty-three iron atom lines Which satisfy requirements for thermometric lines were chosen out of spectra in a wavelength range 3000 to 4000Å.Excitation ternperatures of d.c. arcs and plasma jet flames were determined from the relative line intensities, which were obtained by a simplified procedure to calibrate the sensitivity of the emulsion over the wide range of wavelength, and the Ag-values cited from various literatures. A good agreement was found between the temperatures calculated with the Ag-values based on the NBS Monograph 53 and those with the Ag-values based on the American Institute Physics Handbook (second edition). This suggests that the Ag-values according to these literatures provide relatively reliable values of temperature. Line pairs and published Ag-values recommended for the practicable two-line method were also presented.

    The flash photolysis of thiophenol and its substituted derivatives in degassed organic solvents has been studied and the observed transient spectra were attributed to the corresponding thiophenoxy radicals by means of product analysis, decay kinetics and theoretical calculation of electronic spectra. The molar extinction coefficient and the decay constant of p-chlorothiophenoxy radical have been determined. The electonic spectra of thiophenoxy radicals were calculated with an open shell SCF-MO-CI method in good agreement with the observed specra.

    The flash photolysis of thiophenol and its derivatives in aqueous solutions produced the transients which had the strong absorptions with maxima at 470-600nm.The transients were assigned to the disulfide anion radicals. The decay of the radicals was first-order and the decay constants of some radicals were determined. It was suggested that the transition corresponding to the observed spectra should involve π-electron of rings.
