We observed infrared absorption spectra of tetrahedral silicon tetrafluoride (SiF4) and its clusters in solid parahydrogen. The spectra were assigned by a temporal change of the peak intensity with annealing and previous studies in the gas and other matrices. It was found that the SiF4 monomer does not rotate in solid parahydrogen in spite of its small size and the absence of the permanent electric dipole moment. The dimer spectra are similar to those in the gas phase except for complicated sub-structures. Some other peaks were tentatively assigned to trimer and larger clusters. Clusters with other impurities were also observed.
