  abstract = {The energy dispersion of the D{*} (G') band shows a strong diameter
	dependence according to Raman measurements on double walled carbon
	nanotubes. The Raman shift of the small diameter inner tubes shows
	an average softening. There is an oscillation around an average linear
	behavior with slopes of 108 cm(-1)/eV and 61 cm(-1)/eV for the outer
	and inner tubes, respectively. We show that the experimental observation
	can be reproduced by simple model calculations if the curvature effects
	are taken into account. The phonon softening with increasing curvature
	was proven by first principles calculations. (c) 2007 WILEY-VCH Verlag
