Enhancement Factors

2.3 .Enhancement Factors of Nuclear Overhauser Effect

η = γ_A/2γ_X

Here,   η = Fractional increase in a signal due to NOE.

             γ_A = Gyromagnetic ratio of A- nuclei (saturated)

             γ_B = Gyromagnetic ratio of X- nuclei (observed)

The resulting total intensity I, of the enhanced X-signal is given by⁴:-

I = (1 + η )I

Here,        I = Original Intensity
