By removing the assumption that all hybrid orbitals are equivalent sp " n " orbitals, better predictions and explanations of properties such as molecular geometry and bond strength can be obtained.

Do sp3d and sp3d2 hybrid orbitals look different in shape with spx orbitals ? . all spx orcitals look the same .-- talk ) 09 : 15, 23 May 2011 ( UTC)

For hybrids of s and p orbitals, this is the coefficient ( \ lambda ) multiplying the p orbital when the hybrid orbital is written in the form ( s + \ lambda p ).
24.
In such anions, each atom is at a polyhedral vertex and contributes two electrons to each covalent bond along an edge from their sp 3 hybrid orbitals, the other two being an external lone pair.
25.
In CH 4, four sp 3 hybrid orbitals are overlapped by hydrogen 1s orbitals, yielding four ? ( sigma ) bonds ( that is, four single covalent bonds ) of equal length and strength.
26.
For the oxygens with a double bond to the sulfur, the hybridization would be sp 2-2 hybrid orbitals containing the 2 loan lone pairs, and one containing the ? bond to the sulfur.
27.
The value of " & lambda; j " and direction of p j must be determined so that the resulting orbital can be normalized and so that it is orthogonal to the first hybrid orbital.
28.
If you want to find the actual shapes of sp3d and sp3d2 orbitals, using google images, I turned up this picture : which has pictures of all of the hybrid orbitals from sp up through sp3d2.
29.
In another configuration, known as trigonal configuration, one of the p-orbitals ( say p z ) remains unchanged and three hybrid orbitals are produced by mixing the s, p x and p y orbitals.
30.
Now choose a second hybrid orbital p j " } }, where p j is directed in some way and " & lambda; j " is the amount of p character in this second orbital.
