An interaction between segments, widely separated in sequence
along the chain, that occasionally approach one another during molecular flexing. This type of interaction is closely related to the excluded volume of a segment, the latter quantity reflecting interactions involving segments and solvent molecules. If no confusion can occur, the word 'intramolecular
' may be omitted.
