A method for creating virtual spectral information by orderedcombination of generic DARC primitives isproposed. Structural crowns are generated and define ∼300million potential environments around the8587 available primitives. The associated spectral data areinduced by controlled transfer from spectralmaps characterizing the primitives forming the crown. This virtualenhancement of knowledge fills thegaps inherent to an experimental data bank by defining the potentialinfluence of environments absent fromthis bank on their core primitive.
