In a so-called autopower spectrum, the intensity (square of amplitudes) of the calculated sine/cosine waves representing the surface profile is plotted versus the corresponding wave number (reciprocal wavelength). 

The factor 352 is a useful conversion factor which absorbs Planck s constant h and gives energies directly in kilogram calories, when frequencies co are expressed in wave-numbers (reciprocals of wave lengths expressed in cms.). 

A linear function between the logarithm of the Reynolds number and the logarithm of the film number (reciprocal Kapitza number) at the first appearance of instability of a flowing film was found by Graef [6]. Thereby the film number is defined by the following equation Kr = (P VCgV)...

The IR absorption spectrum is the graphical representation of a measure of energy depending on a measure of wave of the involved radiation. IR practice has established the use of the wave number (reciprocal of the wave length and proportional to the frequency of the radiation) and of the percentage transmission (T%) or absorbance (A), as related to the...

In order to obtain descriptors with uniform length the intensity distribution i(s) is calculated for a fixed number of discrete values of the reciprocal distance s. 

Vgiec and Vxc represent the electron-nuclei, electron-electron and exchange-correlation dionals, respectively. The delta function is zero unless G = G, in which case it has lue of 1. There are two potential problems with the practical use of this equation for a croscopic lattice. First, the summation over G (a Fourier series) is in theory over an rite number of reciprocal lattice vectors. In addition, for a macroscropic lattice there effectively an infinite number of k points within the first Brillouin zone. Fortunately, e are practical solutions to both of these problems. 

Iditional importance is that the vibrational modes are dependent upon the reciprocal e vector k. As with calculations of the electronic structure of periodic lattices these cal-ions are usually performed by selecting a suitable set of points from within the Brillouin. For periodic solids it is necessary to take this periodicity into account the effect on the id-derivative matrix is that each element x] needs to be multiplied by the phase factor k-r y). A phonon dispersion curve indicates how the phonon frequencies vary over tlie luin zone, an example being shown in Figure 5.37. The phonon density of states is ariation in the number of frequencies as a function of frequency. A purely transverse ition is one where the displacement of the atoms is perpendicular to the direction of on of the wave in a pmely longitudinal vibration tlie atomic displacements are in the ition of the wave motion. Such motions can be observed in simple systems (e.g. those contain just one or two atoms per unit cell) but for general three-dimensional lattices of the vibrations are a mixture of transverse and longitudinal motions, the exceptions... 

Note that five significant figures have been retained for the reciprocals of the squares of the quantum numbers because, as you can see in the calculation, two of these figures are lost when the reciprocals are subtracted.
