Notes
| 14) |
Value at T = 310 K. |
| 21) |
Several references are given in the list of Henry's law constants but not assigned to specific species. |
| 68) |
Modarresi et al. (2007) use different descriptors for their calculations. They conclude that a genetic algorithm/radial basis function network (GA/RBFN) is the best QSPR model. Only these results are shown here. |
| 185) |
Value from the validation set for checking whether the model is satisfactory for compounds that are absent from the training set. |
| 186) |
Experimental value, extracted from HENRYWIN. |
