Look up emission bands, black body radiation, emissivity, and absorption spectrum.

If I recall physics correctly, once the radiant heat energy has been absorbed (it is held in the molecule as a bond vibration that is characteristic of the particular frequency of radiation absorbed) it may, instead, be transferred to another molecule as sensible heat - molecule kinetic energy - through intermolecular collisions.
