  2. Nuclear magnetic resonance spectra database - Wikipedia

    en.wikipedia.org/wiki/Nuclear_magnetic_resonance...

    Available through Wiley Online Library [3] (John Wiley & Sons), SpecInfo on the Internet NMR is a collection of approximately 440,000 NMR spectra (organized as 13 C, 1 H, 19 F, 31 P, and 29 Si NMR databases). The data are accessed via the Internet using a Java interface and are stored in a server developed jointly with BASF. The software ...

  3. n-Propyl iodide - Wikipedia

    en.wikipedia.org/wiki/N-Propyl_iodide

    n-Propyl iodide (also 1-propyl iodide or 1-iodopropane) is a colorless, flammable chemical compound. It has the chemical formula C 3 H 7 I and is prepared by heating n -propyl alcohol with iodine and phosphorus .

  4. Nuclear magnetic resonance spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Nuclear_magnetic_resonance...

    A 900 MHz NMR instrument with a 21.1 T magnet at HWB-NMR, Birmingham, UK. Nuclear magnetic resonance spectroscopy, most commonly known as NMR spectroscopy or magnetic resonance spectroscopy (MRS), is a spectroscopic technique based on re-orientation of atomic nuclei with non-zero nuclear spins in an external magnetic field.

  5. Paramagnetic nuclear magnetic resonance spectroscopy

    en.wikipedia.org/wiki/Paramagnetic_nuclear...

    Paramagnetic nuclear magnetic resonance spectroscopy refers to nuclear magnetic resonance (NMR) spectroscopy of paramagnetic compounds. [1] [2] Although most NMR measurements are conducted on diamagnetic compounds, paramagnetic samples are also amenable to analysis and give rise to special effects indicated by a wide chemical shift range and broadened signals.

  6. Two-dimensional nuclear magnetic resonance spectroscopy

    en.wikipedia.org/wiki/Two-dimensional_nuclear...

    Two-Dimensional Nuclear Magnetic Resonance (2D NMR) is an advanced spectroscopic technique that builds upon the capabilities of one-dimensional (1D) NMR by incorporating an additional frequency dimension. This extension allows for a more comprehensive analysis of molecular structures. [1]

  7. Nuclear magnetic resonance decoupling - Wikipedia

    en.wikipedia.org/wiki/Nuclear_Magnetic_Resonance...

    Nuclear magnetic resonance decoupling (NMR decoupling for short) is a special method used in nuclear magnetic resonance (NMR) spectroscopy where a sample to be analyzed is irradiated at a certain frequency or frequency range to eliminate or partially the effect of coupling between certain nuclei. NMR coupling refers to the effect of nuclei on ...

  8. Solid-state nuclear magnetic resonance - Wikipedia

    en.wikipedia.org/wiki/Solid-state_nuclear...

    Solid-state 900 MHz (21.1 T [1]) NMR spectrometer at the Canadian National Ultrahigh-field NMR Facility for Solids. Solid-state nuclear magnetic resonance (ssNMR) is a spectroscopy technique used to characterize atomic-level structure and dynamics in solid materials. ssNMR spectra are broader due to nuclear spin interactions which can be categorized as dipolar coupling, chemical shielding ...

  9. Isopropyl iodide - Wikipedia

    en.wikipedia.org/wiki/Isopropyl_iodide

    Isopropyl iodide is the organoiodine compound with the formula (CH 3) 2 CHI. It is colorless , flammable , and volatile. Organic iodides are light-sensitive and take on a yellow colour upon storage, owing to the formation of iodine .
