Influence of nanodiamonds (ND) of 35 and 100 nm in size, containing NV centers, on the strength of hydrogen bonds under heating of the ND water suspensions in the range of 5–95 °C was studied by Raman spectroscopy. General tendency of both NDs to weaken hydrogen bonds in water was found. Substantial influence of functional state of ND surface on hydrogen bond strength was revealed. An influence of hydrogen bonds on fluorescence properties of the NDs in water suspensions was studied as well. It was found that fluorescence properties of NV centers of 100‐nm NDs are stable with regard to change of their surface state, whereas, a fluorescence intensity of the 35‐nm NDs essentially depends on strength of hydrogen bonds in the suspension.
