Supplementary Material

The data ( Chemical Sample Format .csf files ) concerning the geometrical structures are given there for two purposes : it allows downloadind or mirroring of the paper because mirroring tools are going to download the links given below. Of course, it also permits readers to have the data concerning the geometries, and to visualize geometries with other viewing tools, notably with those provided by Cache Software. methanolH.csf (MethylOxonium C1 ) methanolHsym.csf (MethylOxonium Cs ) ethanolH.csf ( EthylOxonium ) 1-propanolH.csf (1-PropylOxonium) 2-PropylOxonium.csf ( Cs ) 2-propanolH.csf ( C1 CORINA ) 1-butanolH.csf ( 1-ButylOxonium ) 2-ButylOxonium_A.csf ( 2-ButylOxonium C1 CORINA ) 2-ButylOxonium_B.csf ( 2-ButylOxonium Cs ) 2-ButylOxonium.csf IsoButylOxonium_A.csf ( IsoButylOxonium C1 CORINA ) IsoButylOxonium_sym1.csf ( IsoButylOxonium Cs type A ) IsoButylOxonium_sym2.csf ( IsoButylOxonium Cs type B ) IsoButylOxonium_sym3.csf ( IsoButylOxonium Cs type C ) tertbutyloxonium1.csf ( TertButylOxonium C1 CORINA ) tertbutyloxonium3.csf ( TertButylOxonium Cs ) In order to allow downloading or mirroring of the paper, the Java Applet binary is also provided. chemapp.jar
