Bruker NMR Encyclopedia is (still?) available on the website of the University of New South Wales - Sydney, Australia . Since the Encyclopedia is a part of the TopSpin software, I will not be surprised if Bruker tries to shut down this online version of the Encyclopedia. So... have a look before it is too late.
