Science Division Seminar, October 30, 1996, Example of how NMR techniques provide structural information using a simple molecule, Isobutanol, as an example 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. CAS Number: 30899-19-5. Isobutanol. 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- Splitting shows how many protons on adjacent carbons (n-1), Isomers are compounds that have the same molecular formula but which the connectivity of the atoms differ. 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. ECHA C&L Notifications Summary It is more convenient to sweep the magnetic field through the resonances at a fixed frequency, typically 60 MHz.

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. Isomers are compounds that have the same molecular formula but which the connectivity of the atoms differ. Its isomers, the other butanols, include n-butanol, 2-butanol, and tert-butanol, all of which are important industrially.
