- 論文の詳細を見る
The relaxation mechanism near the plastic transition in the low-temperature phase of 1,4-diazabicyclo[2.2.2]octane is attributed to the overall molecular tumbling. The activation energy is 23.0 kJ mol<SUP>−1</SUP>, which is nearly equal to the value of 22.2 kJ mol<SUP>−1</SUP> in the proton NMR in the plastic phase.
