We have measured and analyzed the temperature dependence of extended X-ray absorptionfine structure (EXAFS) spectra of tetrahedral systems MBI4 (M : C, Si, Ge). The EXAFSanalysis by means of the cumulant expansion technique enables one to obtain information aboutforce constants including the third-order anharmonicity. The second-order cumulants obtainedexperimentally are in excellent agreement with the values expected by the vibrational data andthe third-order cumulants have been determined successfully. For the first nearest neighbor (NN)Br -M shells the stretching motions are apparently dominant to describe EXAFS, while for thesecond NN Br -Br shell the bending modes are found to contribute significantly to the cumulantsespecially for the third-order anharmonicity. The obtained force constants are conrpared to eachother and the origin of observed bending anharrnonicity is discussed.
