Microwave spectrum of toluene - SO*: Structure, barrier to internal rotation, and dipole moment
The microwave spectrum of toluene * SO2 was observed with a pulsed beam Fouriertransform microwave spectrometer. The spectrum displays a-, b-, and c-dipole transitions. The transitions occur as doublets arising from the internal rotation of the methyl group. The transitions were assigned using the principal-axis method (PAM) internal rotation Hamiltonian with centrifugal distortions. Assuming a...
متن کاملDipole moment, hydrogen bonding and IR spectrum of confined water.
Drastic changes can take place in the structure, dynamics, and thermodynamics of a fluid when it is confined to spaces of molecular dimensions, as compared to its bulk counterpart. Water confinement in the nanometer-scale channels and pores of inorganic open framework materials, such as zeolites, are of great scientific interest. Zeolites are crystalline aluminosilicates, with various controlle...
متن کاملThe Microwave Spectrum of Imidazole; Complete Structure and the Electron Distribution from Nuclear Quadrupole Coupling Tensors and Dipole Moment Orientation
Spectra have been measured for eleven isotopic forms of imidazole, including single substitutions at each nucleus in turn. A complete restructure is obtained. The ring structure is: N(l)-C(2) = 1.364 A, C(2)-N(3) = 1.314 A, N(3)-C(4) = 1.382 A, C(4)-C(5) = 1.364 A, C(5)-N(l) = 1.377 A, <£N(1)C(2)N(3) = 112.0°, <C(2)N(3)C(4) = 104.9°, <£N(3)C(4)C(5) = 110.7°, <£C(4)C(5)N(1) = 105.5° and <£C(5)N(...
متن کاملMicrowave spectrum, structure, dipole moment, and deuterium nuclear quadrupole coupling constants of the acetylene--sulfur dioxide van der Waals complex
Thirty-three Qand c-dipole transitions of the acetylene-SO, van der Waals complex have been observed by Fourier transform microwave spectroscopy and fit to rotational constants A = 7176.804(2) MHz, B = 2234.962( 1) MHz, C = 1796.160( 1) MHz. The complex has C, symmetry with the C,H, and SO, moieties both straddling an a-c symmetry plane (i.e., only the S atom lies in the plane). The two subunit...
متن کاملThe Microwave Spectra of m-Xylene and m-Xylene-d10. Determination of the Low Methyl Internal Rotation Barrier
The rotational spectra of m-xylene, (CH3)2C6H4, and of m-xylene-d10, (CD3)2C6D4, have been recorded between 6 and 26.5 GHz using pulsed beam Fourier transform microwave spectroscopy. The clue for the assignment of the internal rotation multiplets was the inertial defect derived from the A1A1 species transitions. The rotational constants for m-xylene and m-xylene-d10 are A = 3572.1117(1) MHz / 2...
