Original Measurements
Cullinane, N. M.; Rees, W. T.; Trans. Faraday Soc. 1940, 36, 506-514.
Variables:
Room Temp: Temperature $\pu{K}$
Prepared by:
Method/Apparatus/Procedure:
Mixtures were placed in small capillary tubes. Temperature was slowly varied with ample time given for equilibration. Transition temperatures determined by visual observations. Reported temperatures verified by repetitive measurements.
Source and Purity of Materials:
- Synthesized by the authors, was purified by sublimation and recrystallized from alcohol.
- Purity and chemical source not given, was purified by sublimation and recrystallized from acetone.
Estimated Errors:
Ambient temperature: T/K: ±precision 0.2 (compiler). x1: ±0.002 (compiler).
Components:
- Phenoxanthiin, $\ce{ C12H8OS }$; [262-20-4] NIST WebBook
- Thianthrene, $\ce{ C12H8S2 }$; [92-85-3] NIST WebBook
