It has rutile TiO2 structure,<br>but with a small distortion along the apex oxygen atom.<br><br>My case.qtlup file has the following heading<br><br>Â LATTICE CONST.=Â 8.3560Â 8.3560Â 5.5146Â Â FERMI ENERGY=Â Â 0.50182<br>Â 1048 < NMAT < 1090Â Â SPIN=2Â Â NAT=Â 2Â Â Â Â Â SO 0<br>Â JATOMÂ 1Â MULT= 2Â ISPLIT= 8Â tot,0,1,PX,PY,PZ,2,DZ2,DX2Y2,DXY,DXZ,DYZ,3Â <br>Â JATOMÂ 2Â MULT= 4Â ISPLIT= 8Â tot,0,1,PX,PY,PZ,2,DZ2,DX2Y2,DXY,DXZ,DYZ,3Â <br><br>According to the UG, "The m-decomposed DOS (e.g. pz , py , px ) is<br>given with respect to the local coordinate system", but when I plot<br>DOS of DZ2 for Cr (atom 1) and compare it with Fig. 4 of PRL Vol. 80,<br>4305 (1998), Dz2 looks more like their Dxy. Then I check the rotation<br>matrix of Cr atom (which is the same as in the Appendix of UG) to see<br>whether the decomposition is for the rotated atom, but the rotation is<br>45 degree rotation with respect to the $c$ axis, so there is no way<br>Dz2 could become Dxy.<br><br>Therefore, I wonder whether WIEN2k uses a different local coordinate<br>from the above literature where the z axis is from the Cr at the body<br>center to the apex oxygen.<br><br>I have searched the mail list, but could not find an easy answer. I<br>also tried to simply rotate d orbitals using 5x5 rotation matrix, but<br>I have to know which axis orbitals DZ2,DX2Y2,DXY,DXZ,DYZ use.<br><br>Thanks a lot in advance!<br><br>Best regards,<br><br>Guoping<br><br></div></div></div>
