Please take a look at the attached page. What is the dot before the OH and CH on the page. Is it a single regular electron dot?

Thanks,

Susan

Hi Susan. Yes, this is an electron dot bond. Dots (16) are used to represent this sign. Its meaning will be inferred by the reader, just as in print a midline dot can mean different things.

So is the Nemeth indicator used in Chemistry?

Is the electron dot showed unspaced before the OH and the CH?

The Braille Code for Chemical Notation 1997 is a Nemeth Code document. It expands on the Nemeth Code by giving symbols for chemical notation. It also has a few unique format rules. Electron dot notation is in the Chemistry Code (3.2.1, 4.1.5, and 4.3). The braille symbol (dots 16) represents the single electron dot (3.2.1). It is unspaced. See the attached brf file to see what the first two will look like in the sample you sent, using Nemeth in UEB contexts.

The reader will need to realize that (16) is an electron dot, not a multiplication dot or chemical period. Context should make it clear, just as it does in print where the same midline dot sign is used for all three purposes as well.
