概要
- 論文の詳細を見る
Proton spin-lattice relaxation time T. was measured at 19.5 MHz of p-terphenylin the vicinity of its solid-solid phase transition point. A sharp decrease in T. wasobserved near the transition point and was attributed to the critical fluctuationassociated with the phase transition. The T. was interpreted successfully in terms ofthe order-disorder mechanism by which the central phenylene ring jumps betweentwo stable sites in a double minimum potential well and its motion undergoes acritical slowing down in the phase transition region. The possibility of displacivephase transition was also discussed.
