  A methodology of atomically resolved Land\'{e} g factor mapping of a single
molecule is reported. Mn(II)-phthalocyanine (MnPc) molecules on Au(111) surface
can be dehydrogenated via atomic manipulation with manifestation of tailored
extended Kondo effect, which can allow atomically resolved imaging of the
Land\'{e} g factor inside a molecule for the first time. By employing
dehydrogenated MnPc molecules with removal of six H atoms (-6H-MnPc) as an
example, Land\'{e} g factor of atomic constituents of the molecule can be
obtained, therefore offering a unique g factor mapping of single molecule. Our
results open up a new avenue to access local spin texture of a single molecule.
