Harmonic frequencies, anharmonic parameters, and tetrahedral splitting parameters have been determined for the 76GeH4 molecule, based on experimental data of band centers. As a result, the set of 3 harmonic frequencies, 8 anharmonic parameters, and 8 tetrahedral splitting parameters reproduces 31 initial experimental band centers with a root mean square deviation 0.054 cm-1. Keywords: GeH4, vibrational parameters, local mode model.
