<p><font face="serif">So to use the Morse potential you need the
value of <img style="vertical-align: middle"

one is strictly using the harmonic approximation, the value of <img

if we include the ANHARMONIC correction terms for more accuracy...<br>

<br>
the table I gave you has the first one of these correction terms but
not the second one. If you want it let me know.<br>
<br>
In constructing your plots you will also find the equations found on
page 436 of your text very useful. Don't forget about the ones
inside the paragraphs.<br>
<br>
Finally -- it might make things easier for you if you convert all of
your energies to spectroscopic units -- wavenumbers.<br>

Remember, we will meet in the thunderdome tomorrow morning.<br>
