IR spectroscopy of fluorinated detonation nanodiamond demonstrates that an intense absorption band at ∼1344 cm–1 and two smaller ones at ∼1324 and ∼1258 cm–1 form the extended low wave-number wing of the observed consolidated spectrum in the range of 1100–1400 cm–1. The intrinsic infrared absorption of CFx bonding at the nanodiamond surface sites has been determined after subtraction of the contribution from remaining C–O and C–O–C groups inside the aggregates of tightly-bonded fundamental nanodiamond particles, which had not been subjected to fluorine attack and to their replacement by fluorine containing groups.
