Pardon that -- I was responding to another question.<br>

Yep -- it's back in chapter 9.<br>

your problems where we have to fit the data to the Morse
potential what are the units of the two columns? Do you have
any suggestions at how to get it to fit a Morse potential
other than guessing values for a, De and Re?</div>

The last two columns in table 13.4 are in electron volts. After
putting these things in the same units, use the techniques we used
in class today to come up with initial guess for for De. Table 13.4
already gives you the value of Re which you can use an an initial
guess for that parameter. The only other value is a (or alpha
depending on what reference you are using). With some work at
guessing the value of "a" you should be able to come up with a good
initlal guess that will converge.<br>
