FIELD: chemistry.
SUBSTANCE: invention can be used in the field of elaboration of diamond-based materials for magnetic therapy, quantum optics and medicine. A method of determining an angle of misorientation of diamond crystallites in a diamond composite includes placement of the diamond composite into a resonator of an electronic paramagnetic resonance (EPR) spectrometer, measurement of EPR spectrums of nitrogen-vacancy NV-defect in the diamond composite with different orientations of the diamond composite relative to the external magnetic field, comparison of the obtained dependences of EPR lines with the calculated positions of EPR lines of NV-defect in the diamond monocrystal in the magnetic field, determined by the calculation. After that, the angle of misorientation of the diamond crystallites is determined by an increase of width of EPR line in the diamond composite in comparison with the width of EPR line in the diamond monocrystal.
EFFECT: invention ensures higher accuracy of measurements.
