Thermally activated methyl and t-butyl group reorientation in solids.

Solid State 1 H Spin - lattice Relaxation and Isolated - Molecule and Cluster Electronic Structure Calculations in Organic Molecular Solids: The Relationship Between Structure and Methyl Group and t - Butyl Group Rotation

Rapid Biodegradation of Methyl tert-Butyl Ether (MTBE) by Pure Bacterial Cultures

Two pure bacterial strains capable of rapid degrading methyl tert–butyl ether (MTBE) were isolated from an industrial wastewater treatment plant, identified and characterized. These strains are able to grow on MTBE as the sole carbon and energy sources and completely mineralize it to the biomass and carbon dioxide. The strains were identified as Bacillus cereus and Klebsiella terrigena. Bot...

The relationship between crystal structure and methyl and t-butyl group dynamics in van der Waals organic solids.

We report x-ray diffractometry in a single crystal of 2-t-butyl-4-methylphenol (TMP) and low-frequency solid state nuclear magnetic resonance (NMR) proton relaxometry in a polycrystalline sample of TMP. The x-ray data show TMP to have a monoclinic, P2(1)/c, structure with eight molecules per unit cell and two crystallographically inequivalent t-butyl group (C(CH(3))(3)) sites. The proton spin-l...

A thermally robust di-n-butyl thorium complex with an unstable dimethyl analogue.

Methyl and n-butyl thorium complexes of a rigid 2,6-bis(anilidomethyl)pyridine ligand have been prepared; the n-butyl complex is thermally stable, even at 60 degrees C, while the methyl complexes exhibit a high tendency to eliminate methane via sigma-bond metathesis.

Molecular Motions in Solid [Sb(CH3)4]PF6. A Combined F Nuclear Magnetic Resonance and Quasielastic Neutron Scattering Study

The molecular dynamics of tetramethylstibonium hexafluorophosphate, [Sb(CH3)4]PF6 , is investigated over a broad temperature range. NMR spin lattice relaxation times and the N M R second moments of the *H and F nuclei were determined in the range 8.6 < T/K ^ 332.3 for polycrystalline [Sb(CH 3) 4]PF 6 . The complex cation undergoes isotropic tumbling for T > 2 6 0 K and thermally activated methy...
