- 1952, The Terpenes, addenda to volumes 1 and 2, page 507:
  The configurations around the double bond in the side chain are based on considerations of the Raman spectra, dielectric constants, etc., and on comparatively small differences in reactivity; for example, neo-?-irone is converted into irene less readily than ?-irone, but forms an oxime more rapidly; [...]
- 1964, Samuel Coffey, E. H. Rodd, Martin Frederick Ansell, Chemistry of Carbon Compounds: Alicyclic Compounds, page 177:
  Ruzicka and his co-workers showed that the hydrocarbon irene, obtained on reduction of irone with red phosphorus/iodine, had the structure shown and this was confirmed by synthesis [...]
