Here are a few. (Apologies to all authors whose names have been omitted) 1 Arom. and antiarom.: Schleyer et al, Ang Chem Int Ed Engl, 34 (1995) 334 2 Bond separation E's as an arom. measure: Chestnut, J Comp Chem, 16 (1995) 1227 3 Arom of an annulene: Mitchell and Iyer, JACS, 118 (1996) 722 4 Olefinic vs. arom. character: Sulzbach et al, JACS, 118 (1996) 3519 5 A simple test for aromaticity: Schleyer et al, JACS, 118 (1996) 3519 6 Arom of H clusters: J Phys Chem, 100 (1996) 12299 7 Arom and heterocycles: Schleyer et al, Ang Chem Int Ed Engl, 35 (1996) 2638 8 "Aromaticity Today" M. Glukhovtsev, J Chem Educ, 74 (1997) 132 Some refs to resonance/electron delocalization in benzene. Most are theoretical, concerning the role of the sigma vs. the pi electrons. 1) Claim that the pi electrons are *localized*: Nature 1986, 323, 699; 2) same authors: Chap. in "Valence Bond Theort and Chemical Structure", Elsevier, 1990, pp 287-349. 3) JACS 1993, 115, 10925 4) JACS 1993, 115, 10938 5) JACS 1993, 115, 10943 6) JACS 1993, 115, 10952 7) The Mills-Nixon effect: Ang Chem Int Ed 1994, 33, 1721 8) The Mills-Nixon effect: Ang Chem Int Ed 1995, 34, 1454 9) J Phys Chem 1994, 98, 10048 10) J Phys Chem 1995, 99, 2307 11) J Am Chem Soc 1995, 117, 7760 12) Article on forcing benzene rings to cyclohexatriene struct: Chemical and Engineering News 1996, 1 April, p 27.
