As one frustrated ChemSpy visitor just pointed out our old databases and search tools are currently either dysfunctional or entirely missing. I have been trying to spare time to rebuild the various ChemSpy resources over the last few weeks but at the moment it’s news, views and videos and the databases and search are on the backburner.
If you’re after a molecular mass calculator try here. If you’re after molecular structures try here.
Apologies for any incovenience, I will try and get ChemSpy fully functional as soon as possible.
