Search a property


  • All search strings are right truncated. Thus the search string electr finds electric as well as electronic.
  • If you would like to find properties for given chemical systems, use the preposition "of" to designate the system. For example: Heat capacity of liquids.
  • Alternatively, a property can be chosen from the alphabetic list below.
  • Alle search strings are automatically connected by Boolean AND (restricted search). AND needs not to be entered.
  • The order of search strings is not important.
  • Search is case insensitive, i.e. upper- or lowercase letters are not distinguished.
  • Stop words will be filtered if not marked.
