Hydrogen quasi-linear

Hydrogen fluoride dimer, like with the water dimer, is one of the most frequently studied complexes. Both extensive theoretical and experimental data are available for analysis. The PES of the hydrogen fluoride dimer (see Figs. 15 and 16), if compared with that of water, is simpler two stationary points exist the quasi-linear" structure (see Fig. 15) and the cyclic structure (see Fig. 16).

Because of increased interest in the position of the hydrogen sulfide boundary in recent years, the depth of this feature was studied carefully. It was found that the hydrogen sulfide with formal boundary of 0.3 iM appears in density layer ao = 16.10-16.20 kgm 3 [17,19,26,33,39,40]. According to [40] the concentration of hydrogen sulfide increases from its first appearance defined as 0.3 (jlM quasi-linearly to 300-400 m with a vertical gradient of 0.6-0.7 iM nr1. The more frequent sampling performed during the past few years has allowed us... 

Beyond the optimum length the integrated UV power continues to increase but not nearly so rapidly, tending to a quasi-linear dependence on il (c.f. discussion of 2Y rate for hydrogen). The constant C contains the non-linear coefficients in the form of d ff which takes account of the angles of propagation of the fundamental beam. Thus,... 

An example of a reaction mechanism with five linear steps and only one catalytic cycle is the hydrogenation of benzene, which is supposed to occur via the following mechanism where all the steps are non quasi-equibria (e.g. reversible or irreversible)...
