Methodology:
No experimental details given in paper. Compiler speculates that the transition temperatures were probably determined by visually observing the temperature corresponding to the first crystal formation (or complete liquefication).
Sample Information:
- Purity and chemical source were not specified in paper.
- Purity and chemical source were not specified in paper.
Measurement Errors:
Ambient temperature: T/K: precision ±0.3 (compiler). x1: ±0.002 (compiler).
