Discussion Overview
The discussion centers on the existence of a database for the partition function of CO2 at various temperatures, specifically at 1000K. Participants explore the nature of the partition function, its dependence on temperature, and the parameters involved in its calculation.
Discussion Character
- Exploratory
- Technical explanation
- Debate/contested
Main Points Raised
- One participant inquires about a database for the partition function at different temperatures, suggesting it varies only with temperature.
- Another participant clarifies that the partition function, denoted as Q=Q(N,V,T), does not solely depend on temperature.
- A different participant speculates that the original inquiry might have intended to refer to the partition coefficient instead.
- A later reply discusses the total partition function or state sum, referencing a book that states it depends on temperature and provides expressions for vibrational, rotational, and electronic partition functions that require additional parameters.
- This participant expresses a belief that the partition function is consistent across species, with variations in energy level populations due to temperature, although they acknowledge the possibility of being incorrect.
- Another participant mentions discovering a file (TIPS) that generates partition function values for different species and isotopes using the HITRAN database, which is fitted with Lagrange 4 points fitting based on temperature input.
Areas of Agreement / Disagreement
Participants express differing views on the dependence of the partition function on temperature and other parameters, indicating that multiple competing perspectives exist without a clear consensus.
Contextual Notes
Some assumptions regarding the definitions and calculations of the partition function remain unresolved, particularly concerning its dependence on temperature and the parameters involved in its determination.
