Enhancement Factors ηNOE ans ηINEPT for X {1H} Nuclear Overhauser and INEPT Experiments
a) The maximum possible intensity enhancement is equal to 1+ ηNOE in the extreme narrowing limit
b) For 19F or 31P as polarization source (irradiated nucleus) the factors ηNOE and ηINEPT are reduced by the factor 0.941 in the case of 19F and 0.405 in the other case
