M. Hulman et al., Oscillatory behaviour of the photoselective resonance scattering of singlewall carbon nanotubes, SYNTH METAL, 121(1-3), 2001, pp. 1241-1242
The radial breathing mode around 190 cm(-1) was investigated for excitation
with 30 different laser lines. It exhibits an oscillatory behaviour with r
espect to excitation energy. This oscillations could be traced back to the
periodicity of the van Hove singularities. Using the first and the second s
pectral moments parameters characterizing a diameter distribution can be ev
aluated.
