A previous blog described the Internet as a valuable tool in searching for previous work based on a molecular formula. In addition to searching the Internet “directly”, certain online sites can assist and facilitate the search process. Some of these sites are free while others have a fee.
Be aware that the Internet is full of misleading and often times incorrect data. It is one thing to make a mistake in the elucidation process; it is another to follow someone else’s mistake. As always, the next step is to verify the data and publish once.
