Question

please help.


The overlap integral between a p(z) orbital and an s orbital on an adjacent atom is given by S = S sigma cos Theta. where sigma is the angle of the "bond" to the z axis and Theta = 0 when the s orbital is lying on the p axis. S sigma is the angle independent part of the overlap integral. Plot the dependence of S/S sigma and (S/S sigma)2 on Theta. At which angles would there be the highest overlap between these orbitals? Compare these results to the F2 table entries for the p(z) orbital.

Explanation / Answer

the highest orbital overlap will occur when the angle is zero or 180 degrees.
