Kawakatsuet al.and Kawakatsu introduced a new fifth parameter, ηκ, to describe transverse isotropy (TI). Considering that ηκcharacterizes the incidence angle dependence of body wave phase velocities for TI models, its relevance for body wave seismology is obvious. Here, we derive expressions for partial derivatives (sensitivity kernels) of surface wave phase velocity and normal mode eigenfrequency for the new set of five parameters. The partial derivative for ηκis about twice as large as that for the conventional η, indicating that ηκshould be more readily resolved. While partial derivatives forSvelocities are not so changed, those forPvelocities are significantly modified; the sensitivity for anisotropicPvelocities is greatly reduced. In contrary to the suggestion by Dziewonski & Anderson and Anderson & Dziewonski, there is not much control on the anisotropicPvelocities. On the other hand, the significance of ηκfor long-period seismology has become clear.
