Using a combination of experimental and theoretical techniques we present the dependence of the bandgap\udEg and the spin orbit splitting energy so, with Bi concentration in GaAsBi/GaAs samples. We find that the\udconcentration at which so,> Eg occurs at 9%. Both spectroscopic as well as first device results indicate a type I alignment
