Abstract
Dispersion curves for second mode mantle Rayleigh and Love waves are obtained for the following five earth models; Jeffreys, Gutenberg, Lehmann, 8099 and a new model denoted by Lehmann*. Results for the Love waves agree well with those obtained by Jobert and Satô and others. There is, however, a significant difference for the Rayleigh waves of periods shorter than 70sec between our results and those by Bolt and others. A discussion is made on what this difference is due to.
