A high resolution analysis of C-D vibrational modes on single crystal diamond using Fourier transform infrared spectroscopy is reported. This method has the advantage over high resolution electron energy loss spectroscopy of a far superior resolution (< 1 cm-1 versus approx. 10 cm-1). The inherently low surface sensitivity of the former method was overcome by measuring the IR absorption in the attenuated total reflection mode employing a Ge prism. The use of deuterium instead of hydrogen avoids the interference from airborne hydrocarbon contamination. We present data on the diamond (100) surface that was deuterated in a microwave plasma and subjected to a series of isothermal annealing treatments at 700°C. The C-D stretching mode at 2181 cm-1) and the bending mode at 1054 cm-1 could be followed down to a tenth of a monolayer coverage. From the intensity ratio of these bands measured in s- and p-polarization the essentially perpendicular disposition of the C-D bonds has been inferred.
