As the name suggests, electric resonance experiments make use of electric fields to achieve molecular state selection. Figure 8.25 shows a schematic diagram of a molecular beam electric resonance instrument, which we will discuss in more detail when we describe experiments on the CsF molecule. In contrast to the magnetic resonance apparatus discussed earlier, the A, B and C fields in figure 8.25 are all electric fields. In... 

PARAMETER RANGE COMPARISON. Table I summarizes the parameter ranges of the torqued cylinder apparatus, the resonance apparatus and the DMTA. Since the bulk moduli of the materials under consideration in this paper are much larger than the Young s or shear moduli, the materials are considered incompressible. For incompressible materials, the shear modulus is one third of Young s modulus. Comparisons are then made by converting Young s modulus to shear modulus for the data measured by the resonance apparatus and the DMTA. 

Though the measurement uncertainty of each device has been checked, and care was taken to minimize measurement errors, inaccuracies of measurement cannot be ruled out. The higher peak loss factor for the resonant apparatus for example may be due to vibrational energy propagating into the dangling accelerometer cable. 

A very important feature of EDA-complexes is the fact that in the magnetic field they show the existence of an unpaired electron, i.e. signals in the electron spin resonance apparatus. 

Figure 1.2 illustrates the multiple-lumped resonator apparatus and the associated electronics. A resonator consists of a stack of five cylindrical lumps joined by cylindrically shaped torsional spring elements of smaller diameters. The moment of inertia of each of the four lumps is...

Following WWII, Rabi and I returned to Columbia, Lamb remained there and we were later joined by Kusch. Research resumed quickly. Harold K. Hughes [7] succeeded in making the first resonance apparatus with electric oscillating and deflecting fields and used it to study CsF. Nierenberg revived the old alkali resonance apparatus to study atomic cesium for his thesis. 

The most convenient assay procedure involves measurements of F Txp of samples after addition of known amount of F (Rigo et al., 1979). TI measurements can be obtained by a conventional pulse nuclear magnetic resonance apparatus operating at 16 MHz and equipped with time averaging computer using the 90°-t-90° sequence.

The technique to shift molecular transitions into coincidence with fixed frequencies of a laser is called laser magnetic resonance (LMR). This type of spectroscopy, which is used for studying unstable molecules, was combined with the double resonance technique by Lowe and McKellar. A radiofrequency double resonance cell was placed in the 6-cm gap of the electromagnet of an intracavity laser magnetic resonance apparatus. The Zeeman magnetic field was oriented parallel to the laser light polarization (AM = 0 infrared transitions) and perpendicular to the electric field vector...
