The measurements of the resonance shifts of "Se and "'Te, Iff("Se) andAH("'Tc), have been done for liquid Se-Te mixl:tu'es up to 600'C and 500 bar.A rapid increase in If("Se) at higher temperatures has been observed for theSe-rich mixtures, which is ascribed to the increase in the number of onefold defectstates C7. In Te-rich concentration range there appears the contribution ofconduction electrons to J#("'Te), where the sl:ructure of the liquid mixtureschanges from Se-like to Te-like structure. Near the structural transition region,the pressure derivative of J#("'Te) versus temperature curve shows maximumas a consequence of the collapse of chain structure. It is suggested that Te sitesin the chain rather than Se sites tend to be transformed to threefold coordinatedC3 states by increasing Te concentration or by applying pressure.
