A specific Raman spectrum of carbon spherical shells (onions) synthesized by annealinginduced (T= 1800 K) chipping off the outer carbon layers from 5-nm size diamond particles has been observed. It shows a clearly seen band at 1572 cn-'. Its downshift from the position 1582 cm-' (known for a pure gr
