Bob,
I can get the translated coordinates and frame adjustments from the state
script of your page, so I have no problem loading your adjusted data for
Hen's file. But I have looked at that file for years and said, Boy I'd
like to translate the those coordinates.
So, just as a Jmol learning
load http://wetche.cmbi.ru.nl/organic/cyclohexane/jm/chxinv.xyz
for (var i = 1; i 35; i++) { var j = i+1;compare {model=j} {model=i}
ROTATE TRANSLATE 0.0 }
There are 35 models. This runs through the models, rotating and translating
each model to be the best match to the previous model in the

It sure would be a service to all organic students if someone were to create
a good, interactive web page that draws from Hens' page and shows using Jmol
the smooth transition from chair to chair via half-twist (I was calling this
twist-chair) and twist (I was calling this twist-boat) as well as
Henry, it took a little fixing of Jmol, but I was able to visualize the
symmetry there, and this is what I came up with:
The path takes us from D2d through C2 (twist chair) to D2 (twist boat) to C2
(twist chair) to D2d again. The plane of symmetry is broken immediately with
the first twist, and

Please let me know if that does not work for you.
Bob,

I appreciate a debate on this topic may or may not be suited for the

I'd love a little discusson of this, because I'd like to get this out there.
My understanding is that both are correct -- the boat transition state is
lower than the
Henry, so you are saying you think something is wrong with that pathway.
From what I can see, there are two possible pathways from the chair -- one
with a twist to the left; one with a twist to the right. The
enatiomeric twist is not depicted. (Although I think you could invert the
