What does tautomer mean?
A tautomer is a molecule that exists in two or more structural forms that are interconvertible by the movement of a group or atom. This interconversion can occur through a process called tautomerization, which involves the movement of a group or atom between two or more positions within the molecule. Tautomers are an important concept in organic chemistry, as they can have different physical and chemical properties despite their identical molecular formula. The study of tautomers has led to a greater understanding of the structure and properties of molecules, and has had significant implications for the development of new medicines and materials. Tautomers are a fundamental aspect of molecular chemistry, and continue to be an active area of research.

Etymology of tautomer
The term 'tautomer' was coined in the early 20th century by chemists who were studying the properties of molecules. The word is derived from the Greek words 'tauto' meaning 'same' and 'meros' meaning 'part'. The concept of tautomerism was first described by the German chemist Johannes Thiele in 1899, and has since become a fundamental aspect of molecular chemistry.
Usage notes
Tautomers are typically studied in the context of organic chemistry, and are an important concept in the development of new medicines and materials. The study of tautomers requires a strong understanding of molecular structure and properties, and is often carried out using advanced spectroscopic techniques.
