The electronic configuration of Ti is [Ar]3d24s2 .

In TiCl3 the oxidation state of Ti is +3 while in TiCl2the oxidation state of Ti is +2

In case of TiCl3 there is one d electron present in 3d subshell. When light falls on the Ti3+ complex, the t2g electronis excited to eg level.this excitation take polace in greenish yellow region (≈ 5000 A°), the rest is transmitted. the complementary colour is transmitted which is violet.  The colour due to this transition is called d-d transition.
