Derivative of @FT07376@, \(E_{\text{o}}\), with respect to @W06659@, \(\lambda\). SI unit is \(\text{W m}^{-3}\); common unit is \(\text{W m}^{-2}\ \text{nm}^{-1}\).
Note:
All spectral terms may also be defined as derivatives with respect to frequency, \(\nu\), or wavenumber, \(\tilde{\nu}\), and are referred to, when necessary, as in terms of @W06659@, or frequency or wavenumber, respectively.
