Such efforts have met with limited success, and the reason usually advanced is our lack of understanding of the frequency dependence of molecular NLO properties. In classical electromagnetism, we refer to properties that depend on the frequency of radiation as dispersive and we say that (for example) dispersion is responsible for a rainbow. The blue colour of the sky is a dispersion effect, as is the red sky at night and morning. There is more to it than that, and you might like to read a more advanced text (Hinchliffe and Munn, 1985). 

Parallel to these works, from 1987 onwards I proceeded along a clear line of development that led to my present-day projects. My first conception of this type was a multidimensional sculpture for the University of Trier, a visionary design as a symbol for the interplay of solar energy, clouds and rainbows. The university seemed to me to be exactly the right place for an innovation of this type. I wanted to point the way to the potential positive interaction of environment and energy. 

Thermal distributions of NO(u 2, J, A Ej,) states were observed, wherein the population in any level was determined by the internal energy and the parameter Tr. and independent of spin-orbit state or lambda doublet species. This is in contrast to the rotational rainbows, the propensities for preferential population in the Il(A ) lambda doublet species and the Fj spin orbit state which were observed in direct inelastic scattering of NO/Ag(l 11). 

The Journal of the Optical Society of America for August 1979 is almost entirely devoted to meteorological optics it contains several papers on rainbows, the glory, and ice crystal phenomena. 

A prism is used to separate white light waves into separate wavelength bands that we call the colors of the rainbow. The flat band of colors formed in this way is called the spectrum.

Iridium is a third-row d-block metal and is the heaviest element in group 9. It is a hard, lustrous, silvery metal, discovered by Tennant in 1803 the name iridium derives from the Latin iris (rainbow). The element occurs as a native platinum alloy and in osmiridium (a native alloy of osmium, 15-40%, and iridium, 50-80%). Selected physical and chemical properties of Ir are given in Table 1. It is considered both as a platinum metal and as a precious metal. At room temperature, Ir is particularly resistant to corrosion. 

TAIL OF THE PEACOCK — The Colours of the Rainbow which manifest upon the Matter in the operations of the Stone. To indicate the colours which pass in succession over this Matter, Basil Valentin and many other Philosophers have employed a defined sequence of symbolism. The Raven signifies the Black colour, the Peacock the several hues of the Rainbow, the Swan the colour White, while the Phoenix stands for the Red. 

The native man behind this group is a Shetebo sorcerer. Therefore his cushma is black as are the boas that serve him. He is not a healer, he only kills. He possesses all the knowledge of witchcraft and curses. He works with the darkest beings of hell. Among them are the black yakurunas, the yana-sirenas [black mer maids], the black boa, the sarara [Anhinga anhinga], the black rainbow, the yana-mono [black ape], theyana-tibe [black aquatic bird], etc. 

We shall continue with an example of the method of uniform approximation which is the correct theoretical method for calculating the scattering amplitude, including the interference as well as the rainbow, the glory or the forward diffraction contribution. Only the orbiting has to be described by other methods due to the quite different nature of this phenomenon (see, for instance, Berry and Mount, 1972). 

Iridium forms 4 oxides and 4 chlorides, which are little known. They, have different colours hence the name iridium, from iris, the rainbow. The oxides are IrO, Ir O, IrO, and IrOj, and the chlorides correspond to them.

Just as with the slit, the dependence of the diffraction angle on wavelength means that a circular aperture illuminated with white light will produce a set of coloured rings, rather like miniature circular rainbows. The formula indicates that each ring will have a violet inner edge and a red outer edge. 

Upper and lower bounds for Dq AtH ) are reasonably well established from photo-ionization and flowing-afterglow measurements " 4.2 eV > Dq(AtV ) > 3.4 eV. Several groups have scattered protons oif argon. Wherever the analysis has depended exclusively on the location of the supernumerary rainbows, the derived values for Do(ArH ) are all < 3.4 eV. In one study, " superior resolution has revealed the rapid oscillations in the differential cross section and an analysis based on their location gives Do(ArH ) = 3.85 eV, agreeing with a theoretical calculated value of 3.9 Zero-point-energy...

In 1758 he qualified for the master s degree (Phil. Mag.) with a thesis in pure mathematics and was appointed magister docens (a post peculiar to Uppsala, a kind of assistant to the professor) in natural philosophy. In 1760 (or 1761) he became adjunct (assistant professor) in mathematics and physics. In this period he published on the rainbow, the aurora, the electrical properties of tourmaline, etc. He also made researches in electricity and drew up a table of bodies, each of which when rubbed with a preceding one became negative, but with a subsequent one positive, the strength of the electrification increasing the further apart were the two bodies in the series, an anticipation in frictional electricity of Volta s contact series (see Vol. IV). 

Discovery In connection with the discovery of osmium, S. Tennant in England found an additional metal. When its salts were dissolved in acid different colors were observed. Because of that the new element was given the name indium after iris, rainbow. The discovery year was 1803.
