intramolecular

1 8.7

A change that happens between different parts of the same molecule

adjective
/ˌɪntrəˈmɒlɪkjʊlər/

Specialized

: intramolecular

The reasons for this have to do with the relative magnitudes of intermolecular versus intramolecular forces—that is, the attraction of like molecules for one another compared with that of unlike molecules.

Examples

Some studies involving physical properties are appropriate, including phase changes, crystal structures and formation, intermolecular and intramolecular forces.

Morphology

intramolecular = molecular (transparent) = intra + molecule + ar

Built by productive prefixation: 'molecular' (molecule + -ar) with the clear prefix 'intra-' meaning 'within', so the meaning 'within a single molecule' is directly inferable.

Etymology

Intramolecular combines the prefix intra- ('within') and molecular from molecule ('tiny particle' or 'small part of matter'). So an intramolecular reaction or force happens inside a single molecule, between different parts of that same molecule.
