We will report in this paper a qualitative and quantitative analysis of these bonds. The observation in some plots of an excluded region was statistically analyzed using convex hull and kernel smooting methodologies. A theoretical study at the MP2 level with different basis has been carried out indicating that the nitronyl nitroxide radicals (five electrons) lie just in between nitroso compounds (four electrons) and amine N-oxides (six electrons) as far as hydrogen-bond basicity is concerned. specialized Nitroxide radicals Hydrogen bonds Excluded region CSD MP2 calculations 020 1148 150-161 2017 0022-2860 https://www.documentation.ird.fr/hor/fdi:010070988 10.1016/j.molstruc.2017.06.101 0022-2860 [F B010070988] https://www.documentation.ird.fr/hor/fdi:010070988 https://www.documentation.ird.fr/intranet/publi/2017/09/010070988.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2017-10-03 2023-07-11 fdi:010070988 fre
