Multiatomic hydrogen molecules

Hybrid atomic orbitals are mathematical combinations of the normal atomic orbitals. They are as real as hydrogen-like AOs Hybrid orbitals are an effective way to describe multielectron/multiatom systems, i.e. molecules. They are extremely useful in organic chemistry since the molecules are too large to treat with MO theory and extract a physical picture. 

Dole, Wilson, and Fife, who subsequently published their basic findings in the October 10, 1975 issue of Science, were not quite sure what had happened. In a March 1976 letter, Fife said this work is very preliminary and we do not yet understand the mechanism, or, indeed, the full scope of its potential. One possibility, Fife reasoned, was that molecular hydrogen under pressure scavenges free radicals which are well known to cause some forms of cancer. Free radicals are atoms or multiatom molecules that possess at least one unpaired electron the atom or molecule is not internally balanced in terms of its electron-proton ratio but has excess electrical binding energy. One hypothesis, said Fife, is that destruction of these free radicals makes it possible for natural but weak immune systems of the body to cause the malignancy to regress. ...
