| deuterium | 8.2 × 10-313C = 1.00 | I4 for tetragonal | I = 1 | 1.4 × 10-5 | hydrogen 2 | a = 338, c = 560 pm for tetragonal | < 10-6 | | 1 | 4.1064 × 107 rad T-1 s-1 | A rare heavy isotope of hydrogen. Believed to be the first compound nucleus formed in the infant universe. It was discovered in interstellar space in 1965. Because deuterium is quickly destroyed in nuclear reactions, one view is that most of the deuterium in the universe is primordial. | 9.65 × 10-3 where 1H = 1.00 | 2 | | 15.351 MHz where 1H = 100 MHz; 2.3488 T | μ = 0.8574376 | 1.6 × 10-4 | 2.860 × 10-31 m2 | 2H | Nuclear Magnetic Resonance, water containing deuterium instead of ordinary hydrogen is used as a moderator in nuclear reactors | tetragonal for tetragonal | 2 | 0.015 % |
