The other IR absorption occurs at 666 cm -1 . CO 2 symmetry with \(D_{\infty h}\) CO 2 has a total of four of stretching and bending modes but only two are seen.
Weband lead. Air absorbs essentially none of the radiation. Note that if one planchet gives out more counts per minute than the other one, all that indicates is that the radioactivity of the source is greater. Also, you cannot draw any conclusions about how air absorbs the radiation from this number of counts. Web12 sep. 2024 · Figure 6.2. 1: A blackbody is physically realized by a small hole in the wall of a cavity radiator.
