Highly-resolved photoabsorption spectra of SiX_{4} molecules (with X = H, D, F, Cl, Br), recorded by photoionization in the region of the Si-2p absorption thresholds, are presented. Vibrational fine structure could be resolved in all cases, allowing a derivation of vibrational energies and intra-molecular distances of the core-excited molecules from Franck-Condon fits. In case of the heavier ligand atoms, spectral features arising from thermally-excited vibrational states of the electronic ground state were observed. The results obtained for the various ligand atoms are compared with each other and are discussed in the context of the equivalent-cores approximation.
