The spectroscopic content within optical coherence tomography (OCT) data can provide a wealth of information. Spectroscopic OCT methods are frequently limited by time-frequency trade-offs that limit high spectral and spatial resolution simultaneously. We present spectroscopic spectral-domain optical coherence microscopy performed with a multimodality microscope. Restricting the spatial extent o...

Results of a blind test of photometric redshift predictions against spectroscopic galaxy redshifts obtained in the Hubble Deep Field with the Keck Telescope are presented. The best photometric redshift schemes predict spectroscopic redshifts with a redshift accuracy of |∆z| < 0.1 for more than 68 percent of sources and with |∆z| < 0.3 for 100 percent, when single-feature spectroscopic redshifts...

in order to represent the potential energy function over the whole range of r, many potentialenergy functions have been proposed. in the present paper, we employ many potential energyfunctions, to use numerov method for solving the nuclear schrödinger equation for the ifmolecule, as an example of a heteronuclear diatomic molecules. then we determine thespectroscopic constants eω , e e x ω , e b...

a novel quaternary ammonium-based cationic gemini surfactant (s6) having 1,6 di-bromo hexane as a spacer, have been used and its interaction with insulin in aqueous solution (ph, 7.40) was investigated by several methods including fluorescence spectroscopy, uv-vis spectroscopy, circular dichroism, dynamic light scattering, ζ-potential measurements, conductivity and transmission electron microsc...

We demonstrate a Doppler-free spectroscopic method that we test on Rb and Rb vapor. By using a magnetic field to induce a dichroism on the sample, we generate a dispersive signal with low background, which allows us to lock a diode laser even on small spectroscopic features. We elaborate the advantages of this simple and easy method by comparing it to other methods. PACS. 39.30.+w Spectroscopic...

phytochemical investigation of the dichloromethane extract of the dried roots of ferula badrakema resulted in the identification of one new and six known compounds. known compounds were sesquiterpene coumarins: mogoltacin, feselol, badrakemin acetate, ferocaulidin, conferone and conferol acetate. the new compound was a sesquiterpene, named badrakemonin. the structures of these compounds were el...
