← ScienceWhich consequence results when carbon nanotubes experience oxidation?
A)Raman peaks show D-band increase✓
B)Increased thermal energy transduction
C)Enhanced electron orbital hybridization
D)Improved tensile strength characteristics
💡 Explanation
Oxidation introduces defects by breaking C=C bonds, exciting phonons; because this excites a double resonance Raman process at a defect site, D-band intensity increases; therefore, observation is possible, rather than alternatives which have specific reaction or condition dependencies.
