Energy levels and oscillator strengths have been calculated for the fi
ne-structure transitions among the levels of the (1s(2)) 2s(2)2p(2), 2
s2p(3), 2p(4), 2s(2)2p3s, 2s(2)2p3p, and 2s(2)2p3d configurations of O
III using the CIV3 program. The extensive configuration interaction a
nd relativistic effects have been included while generating the wave f
unctions. The results are compared with other recent theoretical estim
ates, and their accuracy is assessed.
