    • Where NMR methods are not feasible, initiation efficiencies have been inferred from comparisons of ROMP polymer chain lengths with theoretical values. This requires that ring opening be irreversible and intramolecular chain transfer (backbiting) be slow. See, for example: (a) Six, C.; Beck, K.; Wegner, A.; Leitner, W. Organometallics 2000, 19, 4639-4642.
