A homologous series of polyacetylene oligomers having up to 13 double bonds has been prepared, thus allowing, for the first time, an examination of optical properties of polyenes having enough conjugation length to suggest extrapolation to the polyme

We have measured the solid state Raman scattering spectra of a homologous series of linear polyenes, with the number of alternated double bonds varying from 3 to 12. While we find a linear dependence of the Raman shifts of resonantly coupled modes wi

During the early stages of oxidation of (111) NiAl at 1100 °C, an alumina scale forms and undergoes a series of allotropic phase transformations. In the final stages of phase development, the metastable Θ-alumina transforms to the equilibrium α-al

Microscopic examination of the surface of single crystal (111) NiAl during various stages of oxidation at 1100 C in air shows the development of islands composed of rings of different colors.These islands appear to grow in size and eventually impinge

Native Drosophila were periodically captured, dusted with micronized fluorescent dust and released during the summer of 1977 at two locations near Raleigh, North Carolina. Two or three days after each release, flies were collected in baited traps pla

An alternative way of locating these equilibrium points is to specify that the three distances (genotypic frequencies) are to satisfy the relationship f(Aa)2 = 4 x f(AA) x f(aa). [The frequency of AA is denoted by f(AA), etc.] Those populations which

We present detailed measurements of the vibrational and electronic transitions of photogenerated solitons in cis-rich and all-trans polyacetylene prepared by the Shirakawa method. We find that the saturation concentration of excitations on the trans

The probability distribution of z = x modulo n is pertinent in problems where a total of x items is proportioned into lots of n items each, leaving a remainder of z items. This problem arises in genetic linkage analysis; if x denotes the number of ch
