Isomers are compounds that have the same molecular formula but which the connectivity of the atoms differ. H-1 NMR. Isobutanol (IUPAC nomenclature: 2-methylpropan-1-ol) is an organic compound with the formula (CH 3) 2 CHCH 2 OH (sometimes represented as i-BuOH).This colorless, flammable liquid with a characteristic smell is mainly used as a solvent either directly or as its esters. Butanol, C 4 H 9 OH, is a high value C4 alcohol collectively represented by four isomeric structures: 1-butanol, 2-butanol, isobutanol and tert-butanol. CAS Number: 30899-19-5. It is more convenient to sweep the magnetic field through the resonances at a fixed frequency, typically 60 MHz. Splitting shows how many protons on adjacent carbons (n-1), Cambridge Isotope Laboratories, Inc. NMR spectra were recorded at 298 K using 300, 500, or 600 MHz spectrometers ( 13 C{ 1 H} NMR frequencies of 75.5, 126, or 151 MHz, res- Nuclear magnetic resonance (NMR) spectroscopy can measure radio-frequency Zeeman transitions of proton spins in a magnetic field. Science Division Seminar, October 30, 1996, Example of how NMR techniques provide structural information using a simple molecule, Isobutanol, as an example The full spectrum can only be viewed using a FREE account. Isobutanol. Isomers are compounds that have the same molecular formula but which the connectivity of the atoms differ. Empirical Formula (Hill Notation): C 5 H 12 O. Molecular Weight: 88.15. Applications include the study of biomolecule:ligand complexes, free energy calculations, structure-based drug design and refinement of x-ray crystal complexes. The Automated Topology Builder (ATB) and Repository is intended to facilitate the development of molecular force fields for Molecular Dynamics or Monte Carlo simulations of biomolecular systems. Integration shows number of protons. Its isomers, the other butanols, include n-butanol, 2-butanol, and tert-butanol, all of which are important industrially.
