All lasers have the following three fundamental components (see Figure 1). The gain medium, the business end of the laser, is the medium in which excited states are created which will produce stimulated emission. The exciter is the source of energy for production of the excited states in the gain medium. Finally, the optical resonator determines the directionality, wavelength selectivity, optical feedback, polarization, and other characteristics of the stimulated emission from the gain medium. 

Both the active medium and the resonator determine the light frequencies generated. 

Amidinium type resonance determines protonation sites also in some more complex systems, such as cytosine [74] and pterin [75]. Cytosine is protonated on the ring nitrogen N-1 (Katritzky and Waring, 1963) and calculations on the electronic structure of the cation have been published (Denis and Gilbert, 1968). Pterin is... 

The preceding estimate is based on one-fermion theory, so the observed resonance frequency in a fermion beam may be different as a result of fermion-fermion interaction. Therefore, it is strongly advisable that I be tunable over a wide range to search for the actual resonance pattern. The same experiment can then be repeated in a proton, atomic or molecular beam and the RFR effect should be // 2-dependent with a pattern of resonance determined by the novel chemical shift factor Spin-spin interaction between fermions would split the spectrum as in ordinary NMR, but the RFR fingerprint would be unique.

Electron spin resonance determinations of g-values, linewidths, radical densities and saturation properties have been performed on carbon radicals in samples of coal macerals isolated by density gradient centrifugation techniques. These data are compared with elemental analyses and density measurements. Each maceral type exhibits a different ESR signature" which can be understood in terms of the nature of the starting organic and the extent of coalification. 

Unlike the case of the Faraday rotation isolator, even an elementary description of the operational principle of the circulator is not easy, involving as it does the dimensional resonance of the microwave field within the ferrite cylinder. In this context the word resonance does not signify gyromagnetic resonance but a standing-wave resonance determined by the dimensions of the...

Since the chemical shifts of carbon nuclei in the nicotinamide moiety of the di-phosphopyridine nucleotides (NAD and NADH) are almost identical to the tri-phosphopyridine nucleotides (NADP and NADPH). the intensities of the oxidized (NAD ) and reduced (NADH) resonances determine a mean reduction charge of the cells defined by...

These tubes were then subjected to gamma radiation at 0.5 megaroentgen per hour for 87.2 hours. An attempted electron spin resonance determination of the radical content yielded no evidence of the presence of radicals. 

In case of poly(isobutylene-co-P-pinene) the characteristic resonances associated with the gem-dimethyl structures in Ae 6 = 0.8 to 1.1 range provide an ideal diagiK -tic tool for the analysis of dyad distributions. The relative proportion of resonances determined at 6 = 0.8,1.0 and 1.1 reflect the relative proportion of uncrowded, half-crowded and fuUy-crowded gem-dimethyl groups respectively. Thus...

The resonances determined by u l) are shifted and damped by the memory kernel K k, t). Here we analyze the collective excitations in our model liquid by solving the full GLE which incorporates the damping effect. As a model for the memory kernel we employ a simple exponential model described in Sec. 5.2.3. 

The experiments needed to assign the resonances, determine the molecular stmcture, and characterize the cluster electronic stmcture are the same as those employed for paramagnetic metalloproteins in general, " which, in turn, are largely the same as those employed for comparable diamagnetic proteins,with the exception that faster repetition rates and much shorter mixing times are necessary to characterize the cluster environment. Since nuclear relaxation times can vary from 1 ms to several seconds in a cubane a range of experimental...
