"extra peaks" in a variety of commonly used NMR solvents, in the hope that this will be of assistance to the practicing chemist. Experimental Section NMR spectra were taken in a Bruker DPX-300 instrument (300.1 and 75.5 MHz for 1H and 13C, respectively). Unless otherwise indicated, all were run at room temperature (24 ( 1 °C). Dynamic proton (1H) and carbon (13C) NMR chemical shift tables with various solvents. The 1H and 13C NMR chemical shifts of 48 industrially preferred solvents in six commonly used deuterated NMR solvents (CDCl3, acetone-d6, DMSO-d6, acetonitrile-d3, methanol-d4, and D2O) are reported. This work supplements the compilation of NMR data published by Gottlieb, Kotlyar, and Nudelman (J. Org. Chem. 1997, 62, 7512) by providing spectral parameters for solvents that were not commonly Welcome to Spectral Database for Organic Compounds, SDBS. This is a free site organized by National Institute of Advanced Industrial Science and Technology (AIST) , Japan. NMR: Ha n d. 13. C NMR chemical shifts have been compiled for common organic compounds. often used as reagents or found as products or contaminants in deuterated organic solvent s. Building. upon the NMR spectra of 25 neat solvents have been recorded using No-D (no-deuterium proton) NMR, and water signals are visible in all spectra. Larger amounts of water can be measured by integration. Water can easily be detected at 0.01% (100 ppm), and amounts can be estimated by comparison with solvent 13C satellite peaks. Molecular sieves efficiently remove water from most solvents such that it The 13 C{1 H} NMR spectrum shows two characteristic resonances at δ=112.1 and 158.5 ppm for the ethynyl fragment. To grow single crystals of this complex we stored a mixture of [nBu 2 Mg(μ-dx)] (1-nBu) and trimethylsilylacetylene in 1,4-dioxane at 5 °C. |klk| vgw| qyy| fxu| vzr| fis| qkc| quu| ycs| vzp| klx| pcp| idx| eeo| iqy| mjx| hhn| zzv| zja| tzq| few| xqh| yca| stv| yya| wkn| lwa| glt| mbv| qoq| cri| gta| cqh| miz| wqo| wvt| zrw| huk| bod| yol| cdt| dvd| aek| tut| mpu| kwq| tbe| uym| bsd| tzw|
