文摘
- •
Prominent system-density fluctuation (librational) mode at 600−800 cm−1.
- •
Librational mode has marked system-size and temperature dependence; disappears for larger systems.
- •
Persistent system-density fluctuations at 10−11 cm−1 for all systems and temperatures.
- •
10−11 cm-1 mode conjectured to reflects 3 ps timescales for earlier-observed local-density fluctuations.
