A "global fitting" method was developed within the framework of the "SPHETOM" software implemented at the Tomsk Polytechnic University using the GeH4 molecule of T d symmetry as an example. Set of interacting states (so-called octad of interacting states) is chosen as the object of application. Band centers, rotational and resonance interaction parameters of all 24 sub-bands of the octadwere determined for the first time. Obtained information is important both for high-accurate intramolecular
