  abstract = {Single-walled carbon nanotubes (CoMoCat) have been enriched with (6,5)
	tubes via density-gradient ultracentrifugation. Thin solid films
	of quasi-isolated nanotubes were fabricated from a solution of sorted
	nanotubes by vacuum filtration and extraction with water. Optical
	spectroscopy in the vis-NIR region and Raman spectroscopy were used
	to characterize these materials. The experimental studies were supported
	by a theoretical analysis of the electronic and vibrational structure
	of selected (n,m) tubes by using density functional theory. Besides
	the most abundant tubes (6,5), the experimental and theoretical data
	for tubes (6,4), (7,3), (7,5), (8,3), and (9,1) are also discussed.
	A detailed investigation by in situ Raman spectroelectrochemistry
	was focused on the effects of electrochemical p-/n-doping. The experimental
	analysis of the intensities and frequencies of the radial breathing
	mode and the tangential displacement modes were correlated with the
	theoretically calculated optical transition energies and Raman frequencies.
	It was demonstrated that electrochemical charging is a useful tool
	for the study of doping effects on the electronic structure of carbon
	nanotubes.},
