- W2070897023 abstract "T1 ← S0 absorption and T1 → S0 phosphorescence spectra of neat cystalline hexachloroacetone have been analyzed at 4.2°K. From the lifetime and energy the upper state is assigned as 3nπ*. The spectra are sharp compared to other aliphatic ketones, with the 0-0 band at 26 248 ± 2 cm −1. The phosphorescence shows two strong progressions; one involving the CO stretching mode at 1784 cm−1 (x), the other a long progression of at least 8 bands involving a mode at 143 cmt-1 (a). The 143 cm−1 progression forming mode can best be asigned to the CO out-of-plane wagging vibration. The absorption shows the same two strong progressions, reduced in frequency to 1270 cmt-1 and 123 cm−1, respectively, but with the progression in mode a broadened with increasing n. The broadening is interpreted as arising from inversion doublets; the close harmonicity up to n = 5 allowing the potential barrier to inversion to be estimated as > 700 cm−1. A feature of the spectra is the absence of low frequency torsional modes suggesting lack of pseudo Jahn-Teller distortion of the triplet state potential surface. For comparison, the phosphorescence of crystalline hexafluoroacetone was also studied at 4.2°K. The spectrum exhibits broad bandedness with a 00 band tentatively assigned at 26 870 ± 20 cm−1." @default.
