Notes:
In order to enhance research in the field of low-temperature photophysics or photochemistry, a convenient multiple-purpose spectrophotometer system was constructed. This system enabled us to measure the emission (and/or its excitation) and absorption (even under steady-state photolysis) spectra of liquid and solid samples at a temperature ranging from 10 up to 313 K. The spectral resolutions (or the peak separations) were estimated to be ∼0.10–0.31 and ∼1.0–7.3 nm for an emission and its excitation spectra, respectively, recorded at a slit width between 0.05 and 0.5 mm. For an absorption spectrum recorded at a slit width of 0.5 mm, the resolution was still better than that recorded by a commercial spectrophotometer with a bandwidth of 0.2 nm. By recording a number of emission spectra (normalized by the excitation-light intensities at various excitation wavelengths), a contour mapping for the simultaneous intensity representation of the emission and its excitation spectra was also possible.
