Chemputer pseudoelements
The Chemputer recognises formulae such as C4H8Br2 containing only the elements. Some fragments or compounds such as methyl are so common and important that they are given their own special symbols. So, methyl is Me. These special groups are pseudo-elements.
This is the current list of pseudo-elements permitted when entering chemical formulae. Note that in every case, the first letter is a capital letter and all the remaining ones are lowercase. In the chemical literature some of these abbreviations, such as COT or THF, are all in capitals, or all all lowercase, such as cot or thf. In the Chemputer you must use Cot and Thf instead.
