Anotace	In this contribution we report on the grazing angle reflection (GAR) spectroscopy of functionalized diamond surface employing gold optical mirrors coated by nanoporous diamond layers. We show that due to the large surface area of nanoporous diamond layers GAR is sensitive enough for the detection of functional groups on the functionalized diamond surface on the atomic level. Based on IR spectra we compare and discuss the difference in plasma hydrogenated, oxidized, fluorinated, and aminated diamond surfaces. We show clear correlation between FTIR and XPS measurements indicating that the spectra of hydrogenated diamond surfaces are dominated by C-H groups. The IR spectra of oxidized diamond are dominated by hydroxyl and carbonyl groups. The spectra of fluorinated and aminated diamond surfaces confirm the presence of C-F and NH2 bonds, respectively. The obtained results are supported by data from SEM, Raman spectroscopy, current-voltage and wetting angle measurements.
