Using Superscript and Subscript in Fields

[Paul Charlesworth]

Thanks for posting the application, but it didn't seem to work on my 
PowerBook with RR-2 and led to repeated force-quits even when I made a 
build, I am not sure what is wrong at this point.

What I have found so far with messing is that to create the electron 
configurations I would need to code something like this:

[Ne]2<i>s</i><small><sup> 2</sup></small> 2<i>p</i><small><sup> 
2</sup></small> and so on,

The space before the 2 in "<sup> 2</sup>" is needed to prevent the 
italicized "s" from interfering with the superscripted number. I then 
write it in to the field as described in the dictionary using the set 
htmltext command. It looks great, but I will probably need a large 
bottle of something if I have to code 100 elements in this manner. It 
can be done with a lot of copying and pasting, but the scope for error 
is huge. The interesting thing is that once you have been through one 
period, then it is just a matter of duplicating the period and 
adjusting the numbers:

[Ar]3<i>s</i><small><sup> 2</sup></small> 3<i>p</i><small><sup> 
2</sup></small> and so on,


I might try and adapt Jim's scripts, but it would take me longer than 
just coding them by hand, even though it would be a good learning 
exercise. What I think the script needs to do is:

1. Look for the letters s, p, d, f, g, or h that follow a number, 
select that letter and enclose it in <i></i>. I assume this needs some 
kind of search and replace loop until all are done.

2. look for a number that immediately follows the s, p, d, f, g, or h 
and select that number. The number would then need to have a space 
placed in front of it and the two enclosed with 
<small><sup></sup></small>. Again, using a repeat loop.

The problem is preventing the search and replace from picking up the 
next number which should remain as normal text.  1s^2 2s^2 2p^6 and so 
on. By placing a space between each subshell configuration I think it 
would work.

Now I just need to figure it out.  I actually wonder if an applescript 
would work? How hard can it be to learn two separate languages in one 
weekend?
