the g -value gives some information about electronic structure and plays a similar role in EPR to that played by shielding con- stants in NMR. Two factors are responsible for the difference of the g -value from g e . Electrons migrate through the molecular framework by m[r]
information flow and market assistance. Efforts are made to coordinate the activities of diverse federal agencies. An official interagency advocacy network was created that helps U.S. companies win overseas contracts for large government purchases abroad. A variety of agencies now collabor[r]
13.1 ‡ One of the principal methods for obtaining the electronic spectra of unstable radicals is to study the spectra of comets, which are almost entirely due to radicals. Many radical spectra have been detected in comets, including that due to CN. These radicals are produced in comets by[r]
1.3 ARRAY OPERATIONS Array operations refer to element-by-element arithmetic operations. Preceding the linear algebraic matrix operations, * / \ ‘ , by a period ( . ) indicates an array or element-by-element operation. Thus, the operators .* , .\ , ./, .^ , represent[r]

From the results, it can be seen that the two techniques give almost the same answers. 6.2 SINGLE- AND THREE-PHASE AC CIRCUITS Voltages and currents of a network can be obtained in the time domain. This normally involves solving differential equations. By transforming t[r]

(b) Symmetry-adapted linear combinations In the discussion of the molecular orbitals of NH 3 (Topic 10C) we encounter molecular orbitals of the form ψ = c 1 s N + c 2 (s 1 + s 2 + s 3 ), where s N is an N2s atomic orbital and s 1 , s 2 , and s 3 are H1s orbitals. The s[r]
PRACTICAL NOTES... A properly chosen resistor is able to dissipate its heat safely without becom- ing excessively hot. However, if through bad design or subsequent component failure its current becomes excessive, it will overheat and damage may result, as shown in Figure 4–18. One of the sy[r]
The content of this chapter will reveal an interesting and very positive side of the study of a field such as electronic devices and systems—once the basic behavior of a device is understood, its function and response in an infinite variety of configura- tions can be dete[r]
