The NMR solvents used to acquire these spectra contain a maximum of 0 05% and 1 0% TMS (v/v) respectively Since deuterium has a spin of 1 triplets arising from coupling to deuterium have the intensity ratio of 1:1:1 'm' denotes a broad peak with some fine structures It should be noted that chemical shifts can be dependent on solvent concentration and temperature Approximate values The proton NMR spectrum for a compound with formula C 10 H 12 O 2 is shown below The infrared spectrum has a strong band al 1711 cm -1 The normal carbon-13 NMR spectral results are tabulated along with the DEPT-135 and DEPT-90 information Draw the structure of this compound

Analysis of the Proton NMR Spectrum of Toluene: The

The proton NMR spectra of toluene recorded with and without decoupling of the methyl resonance have been completely analyzed in terms of chemical shifts and coupling constants The procedures for the analyses of the spectra are illustrated the results of the different calculations are compared and the values of the spectral parameters obtained are discussed

NMR tubes are available from Stores in Chemistry Department or can be ordered through UCL MyFinance To avoid the instrument downtime you must use NMR tubes free from defects such as a flat bottom cracked chipped or fractured top etc Used NMR tubes are also available from the NMR lab in room LG1B Amount of sample: The sample amount depends on the experiment you are performing

Sometimes we can easily identify the type of proton based on their chemical shift by comparing the value in NMR spectrum table In the above example if a proton shows a chemical shift of 0 9 ppm it will be due to methyl proton while proton with 1 3 ppm as chemical shift will be of methylene proton Compounds with different configuration Configuration is the relative arrangement of the

Several strategies for using enzymes to catalyze reactions leading to the synthesis of relatively simple substituted picolinic acids have been described The goal of the work described here was to synthesize a more complex molecule 6-phenylacetylene picolinic acid [6-(2-phenylethynyl)pyridine-2-carboxylic acid] for use as a potential endcapping agent for aerospace polymers

Toluene-d8 m p -95C Bismuth (Bi 209) NMR: Prof Danna Freedman group has been extensively performing Bi 209 NMR on our Inova 500 MHz system Given that the bismuth 209 frequency (80 3 MHz on I500) is so close to deuterium (76 7 MHz on I500) most of our newer instruments can't do Bi209 NMR without hardware reconfiguration That's why we set up this on I500 which is relatively easier to
