The infrared absorption coefficient in the ordered solid orthohydrogen is calculated by making use of our anharmonic theory for libron (J=1 excitation) and roton (J=3 excitation). The momentum dependence of the transition amplitudes has properly been taken into account in conformity with our formalism. The shape of vibrational bands including J=1,3 rotational excitations is figured out in good agreement with the experiment by Boggs, Clouter and Welsh. A similar study has also been done for the infrared absorption spectra associated with para-hydrogen molecules diluted in the ordered orthohydrogen solid, where the spectral shape to be assigned to J=0⇾2 transition is proved to come from the vibron band in agreement with experiment.
