The "g"-factor, unlike the gyromagnetic ratio, is dimensionless. The magnetic moment has a close connection with angular momentum called the "gyromagnetic effect". Nuclear magnetic resonance detects atoms with different gyromagnetic ratios. The neutron's gyromagnetic ratio, symbol , is . Unlike most nuclei, the gyromagnetic ratio for N is negative. Most common nuclei have positive gyromagnetic ratios such as H and C. Most common nuclei such as H and C have positive gyromagnetic ratios. Additionally, INEPT can accommodate negative gyromagnetic ratios, whereas the common nuclear Overhauser effect (NOE) cannot.
