Infrared spectrum of hydrogen in the condensed phase

A summary of experimental results in which the infrared spectra of solid and liquid hydrogen are obtained using a high resolution spectrometer with a resolution between 0.04 and 0.06/cm is given. Both normal and para-hydrogen samples are used in the experiments. An outline of the theoretical origin...

Summary:A summary of experimental results in which the infrared spectra of solid and liquid hydrogen are obtained using a high resolution spectrometer with a resolution between 0.04 and 0.06/cm is given. Both normal and para-hydrogen samples are used in the experiments. An outline of the theoretical origin of zero phonon transitions which mark the spectrum in the condensed phase is given. Single and double transitions caused by the quadrupole-induced dipole moment dominate the infrared spectrum and include the Q and S lines and their combinations. Results obtained for a few of the double transitions which are more intense than the single transitions and prove the existence of rotational exciton bands in the solid, are presented and compared with the theory by Van Kranendonk (1960). Quadrupolar transitions in the liquid spectrum are also summarized.
