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.
