Absorption bandwidth function calculations

The radiant flux

thermal radiation source through a spectrometer is calculated by multiplying the spectral radiance by the spectral optical conductance, the square of the bandwidth of the spectrometer, and the transmission factor of the entire system (Eq, 3.1-9). Fig. 3.3-1 shows the Planck function according to Eq. 3.3-3. The absorption properties of non-black body radiators can be described by the Bouguer-Lambert-Beer law ... 

As explained before in Eq. (155) fhis value is independenf from fhe convention used to define fhe dipole sfrengfh and only dependenf on the integration range. This is the calculated value foimd by W.T. Carnall in his seminal paper on the intensities of fhe magnetic dipole transitions (Carnall et al., 1968). Note that integration of the absorption signal takes into account the effect of line broadening by the shape function. This is not the case for Bmax) it is very hazardous to work with molar absorptivity if the bandwidth of the peaks are not comparable.
