Part I:
-
What do you notice about the graph on either side of the nucleus?
-
Are the two sides similar?
-
If so, what does that show?
Part II:
-
What do you notice about the shape of the three gaussians?
-
How similar are they?
-
How similar is each one to the simple gaussian we first created?
-
How do they relate to the LCAO? Discuss these questions and compare results
with you lab parter and classmates?
Part III:
Remembering that the STO is the most accurate approximation of the waveform:
-
How accurate is each of the gaussian approximations?
-
Which approximation is the most accurate?
-
Which one takes the most time to compute?
-
How does accuracy relate to number of gaussians used?
-
Which is more important, the time required or the accuracy?
-
How should we decide which approximation to use for a specific project?
