Transmission hydrogen

B. Hydrogen Transmission through Five-Membered Carbon Ring and Hydrogen Encapsulation... [Pg.96]

Nonadiabatic transitions definitely play crucial roles for molecules to manifest various functions. The theory of nonadiabatic transition is very helpful not only to comprehend the mechanisms, but also to design new molecular functions and enhance their efficiencies. The photochromism that is expected to be applicable to molecular switches and memories is a good example [130]. Photoisomerization of retinal is well known to be a basic mechanism of vision. In these processes, the NT type of nonadiabatic transitions play essential roles. There must be many other similar examples. Utilization of the complete reflection phenomenon can also be another candidate, as discussed in Section V.C. In this section, the following two examples are cosidered (1) photochromism due to photoisomerization between cyclohexadiene (CHD) and hexatriene (HT) as an example of photoswitching molecular functions, and (2) hydrogen transmission through a five-membered carbon ring. [Pg.182]

Because of the consequence of a failure in a transmission pipeline system, a pilot-scale R D and demonstration pipeline system may be needed before designing commercial large-scale hydrogen pipeline systems. An International Hydrogen Transmission Test Facility (IHTTF) or International Hydrogen Renewable Transmission Demonstration Facility (IHRTDF) has been proposed for this purpose [4,5]. [Pg.371]
