Preferred Label : derivative spectroscopy;
IUPAC definition : The first (second, ...) derivative absorption spectrum of a molecule is defined as
the first (second, ...) derivative, dA(ν(tilde))/dν(tilde)[d2A(ν(tilde))/dν(tilde)2,
... ] of the absorbance A as a function of wavenumber, ν . Wavelengths may be used
in place of wavenumbers but the shape of the derivative spectra will be slightly different.
When derivative spectra are obtained at low temperature, they are called first (second,
...) derivative low temperature absorption spectra (specifying the solvent, temperature
and solute concentration).;
