The present work performs full bandstructure calculations to investigate thestructural effect and the transition mechanisms of the second harmonicgeneration (SHG) susceptibility of the $\alpha-LiIO_{3}$ crystal. The anomalousinconsistency of associated experimental data of the SHG susceptibility tensoris elucidated to be dominated by the structural effect especially on thetopology of $O$-atoms. On the manipulation of the structural effect, themodification of SHG susceptibility using an external pressure is simulated. Thecalculations of SHG susceptibility tensor are completed at finite frequenciesand the static limit. The comparison with the experiments is also incorporated.On the analysis of the transition mechanisms, the inter-band transition isdetermined to entirely dominate the whole SHG susceptibility at the staticlimit; however, the effect of the intra-band motion is revealed to be asimportant as that of the inter-band transition at finite frequencies.
