Below are pictures of my HNMR and CNMR for salenH2. I have already
assigned some of the protons and carbons myself, but I am having
trouble with the rest. As far as I know, there are 8 unique carbons
and 7 unique hydrogens. The carbons are numbered and the hydrogens
are lettered. I have included a labeled picture of the compound on
each page.
