We have calculated the thermoelectric power, susceptibility and entropy of Bi-2212 and Bi-2201 using the ARPES -derived energy dispersion, a model scattering rate and including a normal-state pseudogap. The doping and temperature dependence is found to closely mimic the experimentally measured data. We have used this approach to examine isotope effects and in particular note that the kink in the dispersion near EF (including its isotope effect) can be probed through the high temperature thermoelectric power.
