Betty, Attached is .doc2 showing 3 samples of braille. Sample #3 is the one I decided on. See what you think. The proofreaders' only comment was to "insert the words 'Shared pair of electrons'." I placed an entry on the TN page alerting the student that circles around shared pairs are omitted in braille. Fred
Hi. Betty asked me to post a suggestion. See the attached document for braille that follows the Chemistry Code for word labels on structures. I included a tn that explains what is being represented in braille. A spurred lead line is inserted from the paired bond to the comment that refers to it.
