Abstract: | Energy transfer from the upper triplet states of aromatic compounds to saturated compounds at 77 K has been investigated. Positions of triplet states of saturated molecules have been estimated in the ranges: 47800–48450 cm?1 for methylcyclohexane, ethylcyclohexane, ethanol and ether, 47320–47800 cm?1 for isopropylcyclohexane and transdecalin, and 48450–50000 cm?1 for isoctane. The radius of the energy transfer sphere for biphenyl-d10 and trans-decalin is found to be 5.1 Å. It is assumed that energy transfer occurs faster than vibrational relaxation. |
