It is necessary to run the source at 80 K to observe this effect. The term "kinetic surface" is coined to describe the family of curves which shows the variation of m/z = 47 intensity and structure as the Ar/O 2/CH 4 mixture varied. A qualitative discussion of the underlying kinetics...
As shown in Fig. 5d, Bi3+/Sb3+@SSC has an obvious absorption peak at 340 nm, most of which is contributed by B i3+. With the increase of Bi3+ ion con- centration, the intensity of the absorption peak at 340 nm is increased. The emission peak of Bi3+@SSC...
At 122 K there are two different Fe3O complexes in the unit cell, both of which are similar in dimensions. As the temperature is decreased from 300 to 122 K, each Fe3O complex becomes more and more distorted in an equilateral triangle. At 122 K one iron ion in each Fe3O complex ...
The shorten- ing of PN bond lengths is likely related to an electrostatic effect (polar bond) which overlaps with P– N r bond [34]. In compounds 1 and 3, the P(1)–N(1) Table 2 Crystallographic data for 1, 2 and 3 Empirical formula Formula weight Temperature (K) Wavelength (A...
Undoubtedly, the comprehension of the great deal of noncovalent forces, which are the basis of highly specific recognition, is crucial for the chemists working in this discipline. For instance, interactions between hosts and guests govern the creation of assemblies with high affinities even in highly...
