Table entries are sorted according to reliability of the data, listing the most reliable type first: L) literature review, M) measured, V) VP/AS = vapor pressure/aqueous solubility, R) recalculation, T) thermodynamical calculation, X) original paper not available, C) citation, Q) QSPR, E) estimate, ?) unknown, W) wrong. See Section 3.1 of Sander (2023) for further details.


436) Calculated based on atmospheric measurements.
437) Calculated using EPI.
438) Calculated using SPARC.
440) Isaacman-VanWertz et al. (2016) refer to Raventos-Duran et al. (2010) as the source, but the quoted value cannot be found there.
441) Calculated using GROMHE.
442) Isaacman-VanWertz et al. (2016) refer to a paper by Hilal et al. as the source, but the quoted value cannot be found there.
443) Calculated using SPARC.
444) Calculated using the bond contribution of HENRYWIN.
