| Popis: |
Fluctuating molecular vibrational-rotational band emission from an unsteady temperature field is formulated in terms of the intensity of the temperature fluctuation and the temperature total sensitivity function of the spectral radiance of a thin, isobaric layer. By examining the contributions of layer-density dilation, Planck's function and molecular spectral absorptivity, it is shown that this total sensitivity function can be either positive or negative with respect to layer temperature depending upon mean temperature and spectral region. The 4.3-μm CO2 band is examined to illustrate these results and a simple quantum mechanical model is presented to estimate these effects in the general case. |
