The possibilities of new sources of energy, such as energy from hydrogen, may also some day become economical, and help to uncouple fossil fuel consumption from economic growth... 

Isotope effects have been used to determine whether the hydride transfer from the enzyme cofactor nicotinamide-adenine dinucleotide (NADH) (reaction (43)) takes place as a hydride ion transfer in a single kinetic step or in a multistep reaction via an uncoupled electron and hydrogen transfer. 

We have discussed, in Chap. A, the Hubbard model for localization vs. itineracy in narrow bands. In this model, it was shown, for a simple case ( hydrogen case) involving one uncoupled electron in a shell, that a splitting of the narrow band in two sub-bands occurs when the Hubbard condition (Uh = W) is not satisfied. The two sub-bands describe two situations ... 

Raman spectra of uncoupled OH and OD stretch bands show a pronounced asymmetry on the high energy side (Walrafen, 1973). Analysis of the band shape reveals contributions from two bands assigned by Walrafen to non-hydrogen bonded and hydrogen bonded oscillators. Addition of sodium perchlorate, a water structure breaker, results in an increase in intensity of the high energy component, consistent with an increase in proportion of free OH.
