Quinoline (1-Benzazene) C9H7N , Mol. Wt. 129.2
The sample was a yellow liquid, transferred to the holder by a pipette.
- height 13.3 mm
- diameter 4.05 mm
- mass 0.191 gm
- density ~ 1.1 g/cc
Measurement Cycle Parameters:
The measurements shown here were done in two "runs". The first run was done in collaboration with Prof. J. Zhang of the Univ. of Ottawa, Ontario, Canada, and used a standard furnace to cycle the sample to 250°C in a 60 psi UHP argon atmosphere, with measurements at 25°C steps. The second "run" used a cryostat, in which the holder and sample were cooled to –70C. The measurements were done during the slow warm up to room temperature.
Comments on the Data:
Our measurements at the lowest frequency ( ~400 MHz) have significant random error, and thus any single measurement must be viewed with caution. We have determined that averaging solves this problem, but under the present multimode operation, this was not possible.
The melting point of quinoline is given as -15°C. The low temperature measurements were done using type N sheathed 20 thou thermocouples touching the holder a few millimetres above the liquid surface.
