The following result is obtained by single calculation at gamma point:<br><br>     Mode symmetry, C_3v (3m)   point group:<br><br>     omega(  1 -  2) =         -7.7  [cm-1]   --> E    L_3        I+R<br>     omega(  3 -  3) =         -2.7  [cm-1]   --> A_1  L_1        I+R<br>
     omega(  4 -  5) =         99.4  [cm-1]   --> E    L_3        I+R<br>     omega(  6 -  7) =        134.5  [cm-1]   --> E    L_3        I+R<br>     omega(  8 -  8) =        413.2  [cm-1]   --> A_1  L_1        I+R<br>
     omega(  9 - 10) =        756.0  [cm-1]   --> E    L_3        I+R<br>     omega( 11 - 11) =        852.2  [cm-1]   --> A_1  L_1        I+R<br>     omega( 12 - 12) =       1058.3  [cm-1]   --> A_1  L_1        I+R<br>
<br><br>According to this, my system has a symmetry. <br><br clear="all"><br>-- <br><pre><b>SINCERELY<br><br>##########################################<br>  Hasan Sahin<br>  Bilkent University<br>  National Nanotechnology Research Center<br>
