abstract

  • The fundamental vibrational infrared-absorption spectrum of solid H2 at 4.2 K has been measured while the sample was irradiated with a 15-MeV proton beam. The Stark-shifted molecular transitions resulting from molecules that are the nearest neighbours of localized electrons have been observed and are contrasted with the same transition previously observed in solid D2. The differences are interpreted as evidence of an interference between the dipole of the localized electron and the charge-induced molecular dipole, a result of a coincidence in the frequencies of the molecular and electronic transitions.
