Question

What are the symmetries of the s, p, d valence orbitals of As, I, and Sn in Asl_3, and SnCl_2?

Answer 1

AsI_3 D_3h point group. As s rightarrow }A_1^1 p_x rightarrow p_y rightarrow } E^1 p_2 rightarrow A''_2 dyz rightarrow dzx rightarrow } E'' dx^2 - y^2 rightarrow a dxy }E' dz^2 rightarrow } A_1^1 Sncl_2 D_infinity h S rightarrow p_x rightarrow p_y rightarrow } The p_z rightarrow } Sigma_u^+ dyz rightarrow dzx rightarrow } pi_g dx^2 - y^2 rightarrow, dxy } Delta g dz^2 rightarrow } Sigma_g^+
