Hi

We recently published a paper in which it was noted that water frozen into
a cold-trap from air at about 1 atm was isotopically depleted.  We thought
that perhaps the depletion resulted from diffusive processes - depleted
water diffusing more rapidly to the freezing surface whilst the remaining
water was carried through.  I've been thinking more about this and was
wondering whether anybody else has any experience or thoughts on this?

Thanks

Hil
