Our research findings

The adiabatic ionization energy of di-substituted benzene derivatives has a "MOP" propensity.

"MOP" propensity: meta > ortho > para (MOP)

o-, m-, p-fluoroanisole

ionization energy: trans-m-fluoroanisole (68304 cm−1) > cis-m-fluoroanisole (67867 cm−1) > o-fluoroanisole (67354 cm−1) > p-fluoroanisole (66437 cm−1) “Rotamers of m-fluoroanisole studied by two-color resonant two-photon mass-analyzed threshold ionization spectroscopy”, Kui-Shiu Shiung, Dan Yu, Hsin-Chang Huang, and Wen Bih Tzeng, J.
