Notes:
The photoabsorption, fluorescence cross sections, and the fluorescence yield of BCl3 are measured in the 45–106 nm region. Fluorescence spectra are dispersed to identify the emitting species. The emission observed at excitation wavelengths longer than 96 nm is attributed to the excited BCl@B|2. The BCl (A–X) emission appears at excitation wavelengths shorter than 97.5 nm. Emissions observed at the thresholds of 88 and 81 nm are attributed to the excited BCl+*3 (C¯ 2A‘2 and D¯ 2E') states, respectively. Emissions from excited B* atoms appear in the 48–64 nm region. In the 88–96 nm region the maxima and minima of the fluorescence cross section are complimentary with those of the BC1+3 ionization yield, indicating where superexcited state(s) exist that decay through competitive channels of fluorescence and autoionization.
