Spectroscopic studies of Lewis acid‐base complexes. III: Vibrational frequencies, assignments and normal coordinate analyses for isotopic varieties of phosphine borane and trifluorophosphine borane
(John Wiley & Sons, Ltd., 1974-04)
Vibrational spectra of the two Lewis complexes, phosphine borane, PH 3 BH 3 , and trifluoro‐phosphine borane, PF 3 BH 3 , have been investigated for several isotopic species preserving C 3 v symmetry. New assignments ...
A NMR Investigation of Structure and Allostery in the Hsp70 Chaperone System.
(2010)
The Hsp70 Chaperone system is a complex molecular machine composed of proteins. It is responsible for assisting in protein folding/refolding/processing and transport. Hsp70 proteins have been historically associated with ...
The design and performance of an ion trap storage--reflectron time-of-flight mass spectrometer
(Elsevier, 1994-02-24)
The design and performance of an ion trap storage--reflectron time-of-flight mass spectrometer (IT--RETOF MS) combination have been explored for detection of ions generated from both internal and external ionization sources. ...
Infrared spectra of high polymers : Part IX. Polyethylene terephthalate
(Elsevier, 1959)
Infrared spectra of polyethylene terephthalate and three of its deuterated analogs have been obtained in the region of 70 to 3600 cm-1, polarized spectra having been obtained down to 330 cm-1. On the basis of analysis of ...
The infrared spectrum of C3O2 : The interaction between [nu]7 and the [nu]2 and [nu]4 vibrations
(Elsevier, 1977-07)
The , , and hot bands of the [nu]4 fundamental of C3O2 in the 1580 cm-1 region were analyzed from tunable diode laser spectra and the ground state to band at 1644 cm-1 from Fourier transform spectra (FTS). The molecular ...
Microwave spectrum and structure of ethylene ozonide-D4
(Elsevier, 1977-04)
Rotational spectra of six isotopic species of ethylene ozonide-D4 have been assigned. The Op---Op distance was calculated six independent ways using Kraitchman's substitution equations, and values between 1.458 and 1.462 ...
Benchmark results for particle transport in a binary Markov statistical medium
(Elsevier, 1989-10)
We give numerical benchmark results for particle transport in a randomly mixed binary medium, with the mixing statistics described as a homogeneous Markov process. A Monte Carlo procedure is used to generate a physical ...
Selection rules for the vibrational spectra of high polymers
(Elsevier, 1957)
With the aid of the Born cyclic postulate, the selection rules for the vibrational modes of a crystalline polymer and an oriented infinite chain-molecule have been discussed. The necessary conditions for the modes to be ...
Total radiances and equivalent widths of Doppler lines for nonisothermal paths
(Elsevier, 1967)
An analytical method similar to that used by (1) on Lorentz lines was applied to the problem of the growth of an isolated Doppler line for the case of nonisothermal paths. The results, given in terms of the total radiance ...
Selective resonance enhanced multiphoton ionization of aromatic polymers in supersonic beam mass spectrometry
(Elsevier, 1991-07-15)
Various polymers have been studied using a pulsed laser evaporation method for volatilizing these species and entraining them into a supersonic jet expansion followed by resonance enhanced multiphoton ionization (REMPI) ...
