Hydrogen continued orbital levels

Note how many distances have to be uniform in order to properly align the hydrogen bonds that stabilize the DNA helix. Here the principle of bonding orbitals is continued to the next higher level of molecular association. The next step, the covalent linkage of the bases of nucleic acid to polynucleotides, is the moment when potential memory is produced from molecules that singularly have no meaning. [Pg.24]

A similar mchanism explains the predissociation of the A2E+ state of the hydrogen halide cations by a 4n state. For HBr+, where the spin-orbit interaction strength is very large, the width of the v = 4 level is equal to 800 cm-1 (exp Penno, et al, 1998, calc. Banichevich, et al, 1992). For HI, the width is so large that the spectrum becomes continuous (Lefebvre-Brion, 1991). [Pg.530]

Bohr reasoned that the energy possessed by the electron in a hydrogen atom and the radius of its orbit are quantized. An amount that is quantized is limited to specific values it may never be between two of those values. By contrast, an amount is continuous if it can have any value between any two values there is an infinite number of other acceptable values (Eig. 11.6). A line spectrum is quantized, but the spectrum of white light is continuous. Bohr said that the electron in the hydrogen atom has quantized energy levels. This means that, at any instant, the electron may have one of several possible energies, but at no time may it have an energy between them. [Pg.307]
