Solid CH4 on Triton and Terrestrial Methane Hydrate

4 Solid CH4 on Triton and Terrestrial Methane Hydrate. - 5.4.1 Radicals in Solid CH4 and on Triton. Methane (CH4) and nitrogen are gaseous molecules on Earth but are frozen and solids under the lowest temperature of 37K at Triton, a satellite of Neptune. Craters of solidified CH4 and N2 and black smoke consisting of gaseous N2 and solid CH4 were discovered by the Voyager II a few km above the ground volcanic eruptions in 1989. 

Natural hydrate obtained from the deep sea core at Blake Ridge, off the eastern coast of USA, was irradiated by y-rays at 77K.131 A signal at g =2.0014 was observed in addition to those due to H° and CHj-. Preliminary work indicates the interaction of CH3 with nearby H20 in the clathrate and/or paired
