Spectroscopic Characteristics of Pentacene In Shpol'skii Matrixes
The Journal of Physical Chemistry A, 2003Absorption, fluorescence, and fluorescence excitation spectra of pentacene were measured in n-heptane, n-nonane, n-decane, n-dodecane, n-tetradecane, and n-hexadecane at temperature 5 K. We found that the band shift in different matrixes is well described by the intermolecular dispersive interactions with the Onsager cavity radius 5.5 ± 0.8 A. Analysis

Spectroscopic Characteristics of Atomic Positive Ions
1985Numerical data are presented for low-lying terms of singly charged atomic positive ions, radiative lifetimes of low-lying resonant excited states and typical parameters of ionic metastable states. The optical transition (n ≤ 2) wavelengths, transition probabilities and radiative lifetimes of atomic ions isoelectronic to hydrogen and helium are also ...

[Spectroscopic characteristics study of morganite from Mozambique].
Guang pu xue yu guang pu fen xi = Guang pu, 2015In recent years, morganite is becoming more and more popular due to its special color. The morganite samples located in the Republic of Mozambique were detailedly analyzed for its basic properties, chemical composition characteristics and spectroscopy properties by laser ablation plasma mass spectrometry (LA-ICP-MS), ultraviolet-visible absorption ...

Spectroscopic and Solubility Characteristics of Oxidized Soots
Aerosol Science and Technology, 1991Spectroscopic and solubility 1 studies of reaction products of soot (black carbon) with O3, NO2/N2O4, and SO2 have revealed a relationship between reactivity and product solubility and structure. A remarkably high solubility of ozonated n-hexane soot has its origin in the formation of anhydride and lactone surface structures and their subsequent ...

Infrared spectroscopic characteristics of bagasse cresol lignin
Polymer Degradation and Stability, 1994Abstract The IR spectra from 200 to 4000 cm −1 of the precipitated bagasse lignin from waste black cresol pulping liquor obtained at various temperatures (160–190°C) after 1·5 h and after various pulping times ( 3 4 −3 h ) at 170°C were studied.

Structural, spectroscopic and device characteristics of octithiophene
Synthetic Metals, 1997Abstract As a step further in the design of efficient organic semiconductors, we report here on the structural, spectroscopic and device characterization of octithiophene (8T), the linear conjugated octamer of thiophene. The X-ray structure and optical spectra under polarized light of the 8T single crystal are described for the first time.

IR Spectroscopic Characteristics of Polyacrylonitrile Copolymer Fibres
Fibre Chemistry, 2002The 1500-1700 cm-1 frequency region in the spectrum of PAN copolymer fibre is structurally sensitive and can be used for the relative characterization of intra- and intermolecular interactions and level of supermolecular structural organization in fibres fabricated in different conditions, in particular, as a function of the nature of the solvent.
