Multi-wavelength Raman and EPR spectroscopies have been used on ball-milled graphite to investigate the effect of varying crystallite size and defect concentration. A correlation between Raman ID/IG intensity ratio and EPR T(1) spin lattice relaxation time of conduction electrons has been discovered which could represent an appealing characterization technique for graphitic materials.

Abstract
Multi-wavelength Raman and EPR spectroscopies have been used on ball-milled graphite to investigate the effect of varying crystallite size and defect concentration. A correlation between Raman ID/IG intensity ratio and EPR T(1) spin lattice relaxation time of conduction electrons has been discovered which could represent an appealing characterization technique for graphitic materials.
