Although ions and ion pairs have similar reactivities in carbocationic systems, their lifetimes during which monomer units can be added are different. The average lifetime of free carbenium ions is the reciprocal of the frequency of association, which is equal to the product of the rate constant of association and the concentration of counteranions [Eq. (69)]. 

Risk and odds are two terms used to express, in numbers, the frequency of association of a risk factor with a disease. Risk ratio (relative risk) and odds ratio are two terms that compare the rate of occurrence of a disease in persons exposed and not exposed to a specific risk factor. Odds ratio is commonly used in case-control studies. Risk ratio tends to be used in cohort studies, "Risk" and "risk ratio" are concepts that are easy to grasp, while "odds" and "odds ratio" are somewhat more difficult.

Figure Al.6.16. Diagram showing the directionality of the signal in coherent spectroscopy. Associated with the carrier frequency of each interaction with the light is a wavevector, k. The output signal in coherent spectroscopies is detemiined from the direction of each of the input signals via momentum conservation (after [48a]).

Most NC-AFMs use a frequency modulation (FM) teclmique where the cantilever is mounted on a piezo and serves as the resonant element in an oscillator circuit [101. 102]. The frequency of the oscillator output is instantaneously modulated by variations in the force gradient acting between the cantilever tip and the sample. This teclmique typically employs oscillation amplitudes in excess of 20 mn peak to peak. Associated with this teclmique, two different imaging methods are currently in use namely, fixed excitation and fixed amplitude. 

For a nonlinear molecule composed of N atoms, 3N—6 eigenvalues provide the normal or fundamental vibrational frequencies of the vibration and and the associated eigenvectors, called normal modes give the directions and relative amplitudes of the atomic displacements in each mode. 

The primary characteristic frequency of an ordinary gas is the rate of coUision f = V/X = ttVnD, where V is the mean particle velocity, and V = [SkT for particles of mass m. Among the special frequencies associated with plasmas, the most notable is the plasma frequency ... 

Second-Generation Antidepressants. The frequency of adverse effects associated with first-generation antidepressants and the lack of patient compliance arising from such adverse effects led to the development of a number of second-generation antidepressants. 

Deficiency of Factor VII is relatively rare and inherited as an autosomal recessive disorder. Deficiency of Factor VII has been reported to be associated with bond abnormal bleeding and thrombotic tendencies. Deep vein thrombosis and pulmonary emboli have been reported in affected individuals. There is a very high frequency of Factor VII deficiency in people with the Dubin-Johnson syndrome, which is a congenital disorder of Hver function. 

Congenital deficiency of Factor XII is inherited as an autosomal recessive trait. Deficiency of this factor is rarely associated with any coagulopathy. It has been observed that people deficient in this factor may have an increased frequency of thromboembolic compHcations.
