β¦ Synopsis
Two special lattice excitations were observed by Welsh et al. in rare-gas crystals doped with hydrogen molecules.
One of these two modes was assigned by Welsh et al. to a localized mode of the hydrogen molecule occupying T. substitutional lattice site. The other lattice absorption is attributed here to resonance mode of the "cornpIes" mo!ecuIc H2Ar.
