This chapter examines the hydrogenic atom, which is a one-electron atom or ion of general atomic number Z. It provides a set of concepts which are used to describe the structures of atoms and of molecules. It analyzes the experimental information from a study of the spectrum of atomic hydrogen and describes the results of solving the Schrödinger ...

Hydrogen atom initiated chemistry
Journal of Molecular Evolution, 1979H atoms have been created by the photolysis of H2S. These then initiated reactions in mixtures involving acetylene-ammonia-water and ethylene-ammonia-water. In the case of the acetylene system, the products consisted of two amino acids, ethylene and a group of primarily cyclic thio-compounds, but no free sulfur.

Hydrogen-Atom Transfer Reactions
Topics in Current Chemistry, 2016The cascade [1,n]-hydrogen transfer/cyclization, recognized as the tert-amino effect one century ago, has received considerable interest in recent decades, and great achievements have been made. With the aid of this strategy, the inert C(sp(3))-H bonds can be directly functionalized into C-C, C-N, C-O bonds under catalysis of Lewis acids, Brønsted ...

Hydrogen Atom Thermal Parameters
Science, 1964Isotropic hydrogen atom thermal parameters for N,N ′-hexamethylenebispropionamide have been determined. They show a definite trend and vary from approximately the same as the mean thermal parameters for atoms other than hydrogen near the center of the molecule to appreciably greater for atoms near the end.

IRE Transactions on Instrumentation, 1961
The atomic hydrogen maser is described. In this device hydrogen atoms in the upper hyperfine state are focused onto the entrance aperture of a Teflon coated quartz bulb in which the atoms are stored for about a second. This bulb is surrounded by a cylindrical radiofrequency cavity; When the cavity is tuned to the hyperfine frequency of atomic hydrogen,

Calculations of electronic energy and static dipole polarizability are reported for the hydrogen atom in the ns states (n=1–6) confined between two impenetrable concentric spheres of inner and outer radii placed at the locations of the radial nodes corresponding to the free hydrogen ns (n=2–7) orbitals.

Symposium - International Astronomical Union, 1985
New aperture-synthesis observations of HI in absorption towards 3C10 with high velocity resolution (0.6 km s-1) and moderate angular resolution (1 arcmin) have been made with the Westerbork Synthesis Radio Telescope. These are an extension of the survey by Schwarz, Arnal & Goss (1980).
