a N.B. the intensity given here is normalised to that of the strongest band in each (nano)diamond sample. b C{111} (C{100}) indicates C-H stretching on the C{111}- (C{100}) surface, and CHx (x=1-3) indicates C-H stretches on corners, edges, defects, etc. (e.g., Chang et al. 1995; Chen et al. 2002).
