This is (+) or (-) Limonene?. The absorptivity is based on functional group affinity and is mostly the physical interactions rather than the valence in nature with non-specific RT conditions. Parametric changes together with physical states of the metal and the terpene play out differently towards absorption. Any terpene with structural features as of limonene will behave in the same manner and check out the metal interactions with these groups, usually activated metals have affinities for hydrogens and certain times the electronegative atoms, although the metal being electron-rich, the electropositive substrates are preferred. Do some searching!

Check Copper (zero valent), Ni and Cr (oxides and other derivatives including reducer capacity derivatives), Silver, Silver Tungstate and Vanadate, Magnesium (including Chlorates), and Zinc as possible metal ligands. Limonene reducing metals/ metal-based derivatives may be the best bet! Thermal Conductivity, at present, seems the technique. Let know your choice and direction.

Well, Keep in touch!
