As ever, Randall has me pondering.
So is there ½ heavy water where only one hydrogen is deuterium and not both?
Is there extra heavy water with tritium?
I mean is there ...
- Water 1+1
- Half heavy water 1+2
- Heavy water 2+2
- Lopsided heavy water 1+3
- A bit heavier water 2+3
- Very heavy water 3+3
And this is ignoring all combinations with "ium" (electron spinning with no proton or neutron) as Randal proposes.
