AbstractWe analyze the dependence of the second-order G'-band profile in terms of their (n,m) indices by measuring the resonance Raman spectra of several semiconducting and metalic isolated single wal carbon nanotubes. We show that this profile is very sensitive to the electronic structure, thus making it possible to get structural (n,m) information and to probe the splitting of the van Hove singularities in the electronic density of states due to the trigona warping effect.

The ν1 band of gaseous carbon dioxide has been studied in pressure-induced absorption at temperatures of ~ 190, ~ 300, and ~ 470 K, over a density range from 0.5 to 300 amagat, and with path lengths from 0.007 to 56 m. The observed temperature variation of the binary absorption coefficient can be satisfactorily accounted for only by adding a quadrupole–quadrupole interaction term to the usual Lennard–Jones model for the inter-molecular potential. The band profile is in agreement with the theory of quadrupole-induced absorption. There is some increase in the intensity of the band near the critical point due to the divergence of the correlation length. A very marked increase in the intensity is possibly prevented by the "cancellation effect".

<p>Vegetable amaranth is considered as one of the most favorite vegetables in the world, especially in the hot and humid tropical regions of the globe. Two of them are most popular i.e., <em>Amaranthus tricolor</em> and <em>Amaranthus blitum</em>, both are represented by a large number of morphotypes or landraces or varieties, which are taxonomically ill-defined, many of them are consumed as palatable vegetables as they look like the conventional cultivars. Due to wide morphological diversity and presence of many synonyms both the species are supposed to represent two species complex or aggregates viz., “Tricolor complex” and “Blitum complex”. Two new species have been identified from their landraces. In the present investigation morphometric analysis along with biochemical and molecular methodologies were applied to explore the relative closeness among few well known, popular vegetables and few less known landraces for better utilization of the crop biodiversity of vegetable amaranths. The experimental data were statistically analyzed and separate Dendrograms were computed on three parameters (Morphology, Isozyme polymorphism and ISSR band profile).The members of “Tricolor complex” were clustered together in a single group along with two newly introduced species <em>A. bengalense</em> (a member of “Blitum complex”) and <em>A. parganensis</em> (a gynomonoecious member of “Tricolor complex”). Tricolor complex represents a plexus of species with varying sexual behavior from gynomonoecy to monoecy and indicates probable origin of monoecious  <em>Amaranthus</em> <em>tricolor </em>varieties or landraces from gynomonecious member like <em>A. parganensis</em> as recent introduction. The study indicated a close alliance between <em>A. bengalense</em>, <em>A. parganensis</em>, <em>A. tricolor</em> landrace and popular <em>A. tricolor</em> varieties which consolidated the feasibility of utilizing the landrace and newly introduced species as potential vegetable.</p>
