Light loses energy via Raman interactions with molecules, exciting rotational and vibrational energy states. A similar energy-loss process exists with light-ATOM interactions via excitation of hyperfine energy states (due to electron-nucleus spin interactions). A large succession of these small energy loss interactions may lead to large red-shifts in cosmological situations. Within the framework of an Incoherent succession of Raman interactions, the possible cosmological applications are explored along with their substantial limitations and restrictions. For very low energy photons (like H:21 cm), no red-shift will occur due to these interactions because these photons do not have sufficient energy to excite Raman interactions. Thus, these Raman interactions will yield red-shifts for high energy (UV/visible) photons, but NOT low energy photons like H:21cm. This is a very definitive astronomical observation that may have been seen in quasars. These effects would occur in addition to any Doppler red-shifts.
