Abstract
Using the pressure dependence of absorption, absorption coefficients and detunings were measured for CO2 pump lines and the strong fat infrared emission in optically pumped D2 O. The P (32) CO2 line was found to be detuned ∼1.5 GHz from the ν2 band transitions 
. The resulting emission lines at 50.3 μm and 66 μm were found to be detuned from their respective transitions by about the same amount. On the basis of these measurements and gain estimates for the far infrared, the resulting emission lines are identified as stimulated Raman emission.
