Discussion Overview
The discussion centers on the transmittance of infrared (IR) radiation through liquid cyclohexane and a quartz viewport, specifically in the context of measuring the temperature of a graphite heater using a pyrometer. The focus includes the compatibility of the IR wavelengths with the properties of cyclohexane and the availability of relevant IR spectra.
Discussion Character
- Exploratory
- Technical explanation
- Debate/contested
Main Points Raised
- One participant inquires about the ability of cyclohexane to transmit IR radiation in the 2-4 micron range through a quartz viewport to a pyrometer.
- Another participant suggests comparing the expected wavelength with the IR spectra for cyclohexane, expressing uncertainty about any overlap.
- A participant clarifies that their chamber is not closed and will condense vapors, while seeking IR curve data for cyclohexane in the range of 30000 to 60000 cm-1 wave number.
- One participant provides links to resources for IR spectra of organic molecules, noting that finding the IR spectra is not difficult.
- Another participant expresses doubt that the available IR spectra cover the specific range mentioned by the original poster.
- A later reply concurs that none of the obtained IR curves include data in the 2-4 micron range.
Areas of Agreement / Disagreement
Participants express uncertainty regarding the transmittance of IR radiation through cyclohexane and the availability of relevant IR spectra. There is no consensus on whether the IR range of interest is covered by existing data.
Contextual Notes
Participants mention limitations in the available IR spectra and the specific wavelength range of interest, indicating potential gaps in data relevant to the discussion.
