Doping with group 16 and 17 elements consistently results in the largest molecule-sheet distances, with d X-O values exceeding 2.7Å. These values exhibit relatively limited variation and do not display any discernible trend across different periods. In contrast, group 13-15 dopants result in significantly shorter molecule-dopant distances, typically ranging between 1.3 and 2.3 Å, with few apparent features. In general, the values of d X-O are comparable for dopants within the same period, and they tend to increase for dopants in higher periods. For instance, adsorption on B-MoTe 2 results in a lower value of d X-O than any of the period 3 dopants, and the same holds true for Al-MoTe 2 compared to period-4 doped sheets, and so forth. The only exception here is N doping, which leads to an unusually large separation between the molecule and the monolayer (1.95 Å) when compared to B and C (≈ 1.3 Å) in period 2 and Al, Si, and P in period 3 (≈ 1.8 Å).
