Infrared spectroscopy is used to investigate the process of molecular hydrogen ortho-to-para (o/p) conversion in solid hydrogen samples doped with small concentrations (10–50 ppm) of hydrogen atoms (H-atoms) as an impurity. The H-atoms are generate

Hydrogen atom quantum diffusion in solid parahydrogen: The H + N

Autor: Fredrick M, Mutunga, Kelly M, Olenyik, Aaron I, Strom, David T, Anderson

Publikováno v: The Journal of chemical physics. 154(1)

The diffusion and reactivity of hydrogen atoms in solid parahydrogen at temperatures between 1.5 K and 4.3 K are investigated by high-resolution infrared spectroscopy. Hydrogen atoms are produced within solid parahydrogen as the by-products of the 19
