Hyperfine strttcttrre constants are jcrecisely c?tlctrl;tied ['or the Is'2s '.51 7,. arxd Is'2p 'P3 /2.3/2states of' tlae "Li attotta arad the 'Be" iota. To describe acctrr;ttely the core jcolarization, xvlaicluis important for the h3zperfine strtrcttrre, XVdX'Cl fttt'rctions are geraerated witla a lar'ge-scale rntrlticonfigtrrational Hartree-Fock rauethod. Corrections dtre to the finite rrtrclear rrrass ?tnd size, El-merelativistic effect, atnd tl'ae qtr?rr'xttnrm electrodynaataaics (QED) ef['ect are consider'ed. The effectof the finite ratrclear size itucltrdes tl'xat of' tlae tauclear naagnetizartion strtrcttrre (Bohr-Weisskopfefl'ect). The corrected valtres of' the znagnetic dipole ?rnd the electr'ic cjttadrtrj.co1e 1a3'perfine strtrcttrre corastants of' Li are detertaained to be An /2 :: 401.7033(790) lN4Hz for the '.5. /2 st?tte, aradA.7. = 45.98429(715) ]VIHz, ,4./2 = -3.13482(55) 1lN4Hz, atacl B37. = -0.208395(10) X'IHz f'ortl'xe P? /2,3 /2 states.
