1-Methylamino-3-(2,4,6-trimethylphenyl)propan-2-ol
Acta Crystallographica Section E, 2011 The methylaminopropyl chain in the title compound, C13H21NO, adopts an extended zigzag conformation and the N atom shows a trigonal coordination. The N atom acts as hydrogen-bond acceptor to the hydroxy group of an adjacent molecule, generating a helical

Evidence of Catalytic Production of Hot Atomic Hydrogen in RF Generated Hydrogen/Helium Plasmas [PDF]
arXiv, 2005 A study of the line shapes of hydrogen Balmer series lines in RF generated low pressure H2/He plasmas produced results suggesting a catalytic process between helium and hydrogen species results in the generation of 'hot' (ca. 28 eV) atomic hydrogen. Even far from the electrodes 'hot' atomic hydrogen was predominant in H2/He plasmas.

Hydrogen Atom in Relativistic Motion
, 2004 The Lorentz contraction of bound states in field theory is often appealed to in qualitative descriptions of high energy particle collisions. Surprisingly, the contraction has not been demonstrated explicitly even in simple cases such as the hydrogen atom.

N′-(5-Bromo-2-hydroxybenzylidene)-3,4,5-trihydroxybenzohydrazide dihydrate
Acta Crystallographica Section E, 2008 The title compound, C14H11BrN2O5·2H2O, crystallizes as hydrogen-bonded sheets. The 2-hydroxy group on the benzylidene group forms an intramolecular hydrogen bond to the N atom of the C=N double bond.

ON THE CONTINUOUS SPECTRUM OF THE HYDROGEN ATOM [PDF]
Proceedings of the National Academy of Sciences, 1929 The purpose of the present paper is to obtain expressions for the intensities in the continuous spectrum of atomic hydrogen suitable for numerical calculations. This purpose is accomplished by means of a new integral representation for the wave function in this special case.

Beyond the classical thermodynamic contributions to hydrogen atom abstraction reactivity
Proceedings of the National Academy of Sciences of the United States of America, 2018 Significance Hydrogen atom abstraction reactivity is a key property of many important biological and synthetic compounds that depends on their proton-coupled reduction potentials.

The Hydrogen Atom of Bohr II: Mean Lifetime of an Ensemble of Excited Hydrogen atoms [PDF]
arXiv, 1999 "Does God play dice with the Universe?" The natural width of excited hydrogen atoms are found using the Bohr's model of this atom and de Broglie's ideas. The mean life time of the excited states is a characteristic only of a statistical ensemble of many atoms.
